+%
+% The \thispackage package offers three possibilities for typesetting

-% \subsection{Tables of Collected Rows}\label{sec:collected-tables}
%
-% As an alternative to producing a table within a single environment,
-% the \thispackage package offers a way to scatter individual
-% rows throughout a document and display the full table later. This
-% method can be useful when table rows are strongly connected to
-% portions of text outside of the table. The method then allows
-% specifying the rows together with the connected text rather than
-% separately in the table environment.
-% Table types for this method are defined via |\NewKeyValTable| as
-% previously described.
+% \subsection{Tables of Collected Rows}\label{sec:collected}
+%
+% The content of a table's rows might logically belong to locations that
+% are scattered throughout a document, e.g., to individual sections of
+% the document. In this situation, it can be convenient to have the rows
+% specified close to the locations their contents belong to, instead of
+% specified in the table environment.
+%
+% The following example illustrates the use of this feature for taking
+% and collecting notes in a document:
+% \begin{LTXexample}[width=0.475\hsize,morekeywords={NewCollectedTable,CollectRow,ShowCollectedTable}]
+% \NewKeyValTable{Notes}{type; text}

+% Lorem ipsum dolor sit amet, \ldots
+%
+% \section{Analysis}
+% \CollectRow{notes}{type=task, text=proofread Analysis}
+% Lorem ipsum dolor sit amet, \ldots
+% \end{LTXexample}
+% See \cref{sec:referencing} on how to (automatically) include
+% references to, e.g., section or page numbers in tables.
+% The key macros (highlighted in bold font) used in the example are the
+% following three.
+%
+% \NiceDescribeMacro{\NewCollectedTable}{\marg{cname}\marg{tname}}
+% This macro defines the name \meta{cname} for a new collection of
+% rows. The collection is associated with the table type \meta{tname}.
+% This macro must be used before |\CollectRow| for a \meta{cname}.
+%
+% \NiceDescribeMacro{\CollectRow}{\oarg{options}\marg{cname}\marg{content}}
+% This macro adds the row content \meta{content} and row options
+% \meta{options} to the row collection \meta{cname}.
+%
+% \NiceDescribeMacro{\ShowCollectedTable}{\oarg{options}\marg{cname}}
+% This macro typesets a table of the row collection \meta{cname}, with
+% the table options \meta{options}.
+% The table includes rows that are collected only afterwards in the
+% document. For this, \hologo{LaTeX} must be run at least two times.
+%
+%
+% \subsection{Sourcing Rows From a File}
+%
+% Rather than specifying the rows of a table inside a |KeyValTable|
+% environment, the rows can also be sourced from a file.
+% More concretely, this file must consist of the |\Row| macros that
+% specify the content of the rows.
+% For information on how to source rows from CSV files, see
+% \cref{sec:CSV}.
+%
+% \NiceDescribeMacro{\ShowKeyValTableFile}{\oarg{options}\marg{tname}\marg{filename}}
+% This macro produces a |KeyValTable| environment of type \meta{tname}
+% whose content is taken from the file \meta{filename}.
+% The \meta{options} specify the table options, which are directly
+% passed to the options argument of the |KeyValTable| environment.
+%
+% \begin{LTXexample}[morepreset=\RecipePreset,morekeywords={ShowKeyValTableFile}]

+%
+% \subsection{Tables of Collected Rows (Legacy Interface)}
+%
+% This section documents legacy functionality of \thispackage, that is
+% now superseded by the functionality described in \cref{sec:collected}.
+% The legacy functionality compares to the new functionality as follows:
+% \begin{itemize}[noitemsep]
+% \item Rows must be collected \emph{before} the place in the document
+% where they are displayed in a table.
+% \item For each table type, there can be only one collection of rows.
+% After the collection has been typeset in a table the collection is
+% emptied again.
+% \item Row content is not written into the aux file. This might be
+% relevant for very large tables.

+%
+% The \thispackage package is carefully designed to take the values of
+% counters such as the page counter and the section counter from the
+% point in the document where |\CollectRow| is used.
+% At the same time, the table row counters are taken from the point
+% inside the respective table. This applies to |\thekvtRow| as well as
+% to |\arabic{kvtRow}| and other counter formats.
+% For customizing this behavior, the following three macros can be used.
+%
+% \NiceDescribeMacros{2}
+% {\kvtDeclareTableMacros}{\marg{macro-list}}
+% {\kvtDeclareTableCounters}{\marg{counter-list}}
+% These macros take a comma-separated list of macros (respectively

+% A macro or counter declared this way is expanded only inside the table
+% environment and not at the point where |\CollectRow| is used.
+% The \thispackage already declares |\thekvtRow|, |\thekvtTypeRow|, and

+% and |kvtTotalRow| as table counters.

+%
+%
+% \section{Changing the Appearance}
+%
+% The appearance (e.g., colors, rules) of a table can be changed at
+% the level of the overall table as well as for individual rows,
+% columns, and cells.
+%
+% \subsection{Table Appearance}\label{sec:TableAppearance}
+%
+% The appearance of a table can be configured through the \meta{options}
+% parameters of
+% \begin{itemize}[nosep]
+% \item |KeyValTable|, |\ShowKeyValTable|, and |\ShowKeyValTableFile|
+% (affecting the particular table),
+% \item |\NewKeyValTable| (affecting all tables of the table type), and
+% \item |\kvtSet| (affecting all tables).
+% \end{itemize}
+% In this list, the former take precedence over the latter. That is,
+% table options override table type options and table type options
+% override global options for all tables.
+%
+% In each case, \meta{options} must be specified as a comma-separated
+% list of \meta{property}|=|\meta{value} pairs.
+% The following \meta{property} keys can be configured.
+%
+% \NiceDescribeKey{shape}
+% {vals={multipage,onepage,tabular,tabularx,longtable,xltabular,tabu,longtabu},
+% init=multipage}
+% This property specifies the table's shape. For \meta{value}, the
+% package currently supports |multipage| and |onepage| as well as
+% |tabular|, |tabularx|, |longtable|, |xltabular|, |tabu|, and
+% |longtabu|. In case of |multipage|, the table may span multiple pages
+% and on each page, the column header is repeated. In case of |onepage|,
+% the table does not split into multiple pages. The remaining values
+% use the respective environment for producing the table (see
+% \cref{sec:AltTabEnv} for the effect).
+%
+% \NiceDescribeKey{width}{vals=\vmeta{dimension}, init=\cmd\linewidth}
+% This property specifies the width of the table, if the selected
+% |shape| supports it (see \cref{sec:AltTabEnv}).
+%
+% \NiceDescribeKey{showhead}{vals={true,false}, init=true}
+% This property specifies whether the header row shall be shown. The
+% \meta{value} must be a Boolean (i.e., |true| or |false|), where |true|
+% specifies that the header row is shown and |false| specifies that the
+% header row is not shown.
+%
+% \NiceDescribeKey{showrules}{vals={true,false}, init=true}
+% This property specifies whether top and bottom rules as well
+% as a rule below the header row are drawn (|true|) or not (|false|).
+%
+% \NiceDescribeKey{headalign}{vals={\vmeta{empty} or \vmeta{coltype}}, init=\vmeta{empty}}
+% This property specifies the alignment for header cells. If left
+% empty, each header cell receives the same alignment as the respective
+% column.
+%
+% \NiceDescribeKey{headbg}{vals=\vmeta{color}, init={black!14}}
+% This property specifies the background color of the header rows. The
+% \meta{color} must be a single color specification that is understood
+% by the \pkgname{xcolor} package. The \meta{color} is passed directly
+% to the \cs{rowcolor} macro. If \meta{color} is empty, then no
+% background color is produced for the header row.
+%
+% \NiceDescribeKey{headformat}{vals=\vmeta{single argument macro}, init=\vmeta{"identity"}}
+% This property specifies a format to be applied to all header cells.
+% The value specified for the |headformat| key is used to format each
+% header. The value can be a macro that takes once argument, through
+% which it is provided the header (as specified in the column's |head|
+% property). Initially, an "identity" macro is used, meaning that each
+% |head| is taken without change.
+%
+% \NiceDescribeKey{rowbg}{vals=\vmeta{color}, init={white..black!10}}
+% This property specifies the background colors of content rows. The
+% \meta{value} for this property must be of the format
+% \meta{oddcolor}|..|\meta{evencolor}. The first row after the header is
+% colored with \meta{oddcolor}, the second row with \meta{evencolor},
+% and so forth. Both colors must be understood by the \pkgname{xcolor}
+% package. If \meta{color} is empty, then no background color is
+% produced for content rows.
+%
+% \NiceDescribeKeys{2}
+% {norowbg}{vals={true,false}, init=false, def=true}
+% {nobg}{vals={true,false}, init=false, def=true}
+% These properties are shorthands for |rowbg={}| (turning off
+% background colors for content rows) and, respectively, for
+% |rowbg={},headbg={}| (turning off background colors for header rows
+% and for content rows). Using these options without a value is
+% equivalent to using |true| for the value. For instance, |nobg| is
+% equivalent to |nobg=true|.
+%
+% \vref{fig:TableOptionExamples} demonstrates the \meta{options} in
+% examples.

+%
+%
+% \subsection{Column Appearance}
+%
+% Column appearance is configured through the parameters |align|,
+% |head|, |format|, and |default| of columns in |\NewKeyValTable|.
+% For the |format|, the following macro exists to ensure proper height
+% and depth of rows even if the content itself is more narrow.
+%
+% \NiceDescribeMacro{\kvtStrutted}{\oarg{inner}\marg{arg}}
+% This macro places a |\strut| before \meta{arg} and a |\strut| after
+% \meta{arg}. This has the effect that the first and last row of
+% \meta{arg} obtain a "natural" height and depth even if their content
+% is smaller.
+% The second |\strut| is omitted when it would cause a new line to be
+% produced.
+% See \cref{sec:row-numbering} for an example.
+%
+%
+% \subsection{Row Appearance}\label{sec:RowOptions}
+%
+% Through the \meta{options} argument of the
+% |\Row|
+% and the
+% |\KeyValRow|
+% macros, the appearance of rows can be configured.
+% As with other option arguments of the \thispackage package, the
+% options must be a comma-separated list of key-value pairs.
+% The following options are supported.
+%
+% \NiceDescribeKey{hidden}{vals={true,false}, init=false}
+% This property specifies whether the row shall be hidden (|true|) or
+% not (|false|). If only |hidden| is used without a value, this is
+% equivalent to |hidden=true|.
+%
+% \NiceDescribeKey{bg}{vals=\vmeta{color}, init=\vmeta{empty}}
+% This property specifies the background color for the particular row.
+% If this option is not specified (or set to an empty value
+% explicitly), the background color is determined by the |rowbg|
+% option of the table.
+%
+% \NiceDescribeKeys{3}
+% {above}{vals=\vmeta{dimension}, init=\vmeta{empty}}
+% {below}{vals=\vmeta{dimension}, init=\vmeta{empty}}
+% {around}{vals=\vmeta{dimension}, init=\vmeta{empty}}
+% These properties specify extra vertical space above and,
+% respectively, below the row. The |around| property is a short-hand
+% for setting both, |above| and |below|, to the same value.
+% Note that the vertical space is currently not colored with the
+% row's background color but with the page's background color.
+% The argument, if provided, is directly passed to |\vspace|.
+%
+% \NiceNote{Initial values for all row options can be set with
+% |\kvtSet{Row/|\meta{option}|=|\meta{value}|}| (see also
+% \cref{sec:kvtSet}).}
+%
+% The following example demonstrates the options.
+% \begin{LTXexample}[morepreset=\RecipePreset,morekeywords={hidden,above,bg}]
+% \begin{KeyValTable}{Recipe}
+% \Row{amount=150g, ingredient=ice cream,
+% step=put into bowl}
+% \Row{amount= 50g, ingredient=cherries,
+% step=heat up and add to bowl}
+% \Row[hidden]{amount=25g, ingredient=cream,
+% step=decorate on top}
+% \Row[above=1ex,bg=Gold]{
+% step=serve with a smile}
+% \end{KeyValTable}
+% \end{LTXexample}
+%
+% \subsubsection{Row Styles}
+%
+% Rather than specifying properties for individual rows, \thispackage
+% also supports named \emph{row styles}.
+%
+% \NiceDescribeKey{style}{vals=\vmeta{list of style names}, init=\vmeta{empty}}
+% Through this property of rows, a list of styles can be applied to the
+% row. Each style must have been defined with |\kvtNewRowStyle| before.
+%
+% \NiceDescribeMacro{\kvtNewRowStyle}{\marg{name}\marg{row-options}}
+% This macro declares a new row style with the given \meta{name} and
+% defines it to be equivalent to using the given \meta{row-options}.
+% The \meta{name} must not already be defined.
+%
+% \NiceDescribeMacro{\kvtRenewRowStyle}{\marg{name}\marg{row-options}}
+% This macro re-defines an existing row style \meta{name} with new
+% \meta{row-options}.
+%
+% The following example produces the same output as the previous
+% example, but uses row styles.
+%
+% \begin{LTXexample}[morepreset=\RecipePreset,morekeywords={style,kvtNewRowStyle}]
+% \kvtNewRowStyle{optional}{hidden}
+% \kvtNewRowStyle{highlight}{above=1ex,bg=Gold}
+% \begin{KeyValTable}{Recipe}
+% \Row{amount=150g, ingredient=ice cream,
+% step=put into bowl}
+% \Row{amount= 50g, ingredient=cherries,
+% step=heat up and add to bowl}
+% \Row[style=optional]{amount=25g,
+% ingredient=cream, step=decorate on top}
+% \Row[style=highlight]{step=serve with a smile}
+% \end{KeyValTable}
+% \end{LTXexample}
+%
+% \NiceNote{The \meta{row-options} in |\kvtNewRowStyle| can be left empty.
+% In this case, the row style does not have any effect on the appearance
+% of rows. However, the style can already be used for "tagging" rows and
+% the final options for the style can be configured at a later point in
+% time.}

+%
+% \section{Customizing the Layout}
+%
+% The \thispackage package provides some means for altering tables
+% beyond those described in the previous sections.
+% Those means are described in the following.
+%
+% \subsection{Custom Table Headers}\label{sec:CustomHeaders}
+%
+% By default, a table type defined by |\NewKeyValTable| includes a
+% single header row and each column of the table type has a header cell
+% in this row.
+% Through the optional \meta{layout} parameter of |\NewKeyValTable|,
+% one can define multiple header rows and can define header cells that
+% span multiple columns.
+%
+% The following two examples illustrate how the |headers| key in the
+% \meta{layout} parameter can be used for specifying custom
+% headers.\footnote{In \thispackage v1.0, the \meta{layout}
+% parameter specified \emph{only} the headers and did not use a
+% \texttt{headers} key for this. For compatibility, this can be enabled
+% with the \texttt{compat=1.0} package option.}
% The first example produces a single header row in which two columns
% are grouped with a single header, one column has a normal header, and
% in which one column is not provided with a header.

+%
+% \NiceDescribeKey{align}{vals={\vmeta{alignment-letter},\vmeta{empty}}, init=c}
+% This property specifies the alignment of content in the header cell.
+% The \meta{value} can be set to any column alignment understood by
+% the underlying table environment used (see \cref{sec:AltTabEnv}).
+% This particularly includes |l|, |c|, |r|, and |p|, as well as |X|
+% for some of the table environments.
+% The initial value can be modified with
+% |\kvtSet{HeadCell/align=...}|.
+%
+% \NiceDescribeKey{head}{vals=\vmeta{text}, init=\vmeta{colspec}}
+% This property specifies the content of the header cell.
+% The initial value for this property is the column specification,
+% i.e., "\meta{col}|+|\ldots|+|\meta{col}".
+%
+%
+% \subsection{Column Spanning}
+%
+% The \thispackage package supports column spanning via "column
+% groups". A column group is a collection of adjacent columns, has
+% its own name, and can be assigned a value just like "normal" columns
+% can be.
+% The following example demonstrates how column groups can be defined
+% and be used.
+%
+% \begin{LTXexample}[morekeywords={colgroups}]
+% \NewKeyValTable{AltRecipe}{
+% amount: align=r, format=\textbf;
+% ingredient: align=l;
+% step: align=X;
+% }[colgroups={
+% all: span=step+amount+ingredient
+% }]
+% \begin{KeyValTable}{AltRecipe}
+% \Row{amount=150g, ingredient=ice cream,
+% step=put into bowl}
+% \Row{amount= 50g, ingredient=cherries,
+% step=heat up and add to bowl}
+% \midrule
+% \Row{all=serve with a smile}
+% \end{KeyValTable}
+% \end{LTXexample}
+%
+% As the example shows, column groups are defined through the
+% |colgroups| key of the second optional argument of |\NewKeyValTable|.
+% This key expects a semicolon-separated list of individual column
+% groups definitions.
+% Each such definition takes the same shape as a normal column
+% definition -- that is, first the name of the column group, then a
+% colon, and then a comma-separated list of column properties.
+% The properties that can be set are the following.
+%
+% \NiceDescribeKey{span}{vals=\vmeta{plus-separated columns}}
+% This property specifies which columns the column group shall span, as
+% a plus-separated list of column names. Some or all of the columns can
+% be hidden. All the displayed columns must be adjacent in the table,
+% though.
+%
+% \NiceDescribeKeys{2}
+% {align}{vals={\vmeta{alignment-letter},\vmeta{empty}}, init=c}
+% {format}{vals=\vmeta{single argument macro}, init=\cmd\kvtStrutted}
+% These properties are analogous to the respective properties of normal
+% columns. The only difference is that the initial column alignment of
+% column groups is "|c|" while the alignment of normal columns is "|l|".
+%
+% \NiceNote{Initial values for all the |align| and |format| options can be
+% set with |\kvtSet|, via the |ColGroup/align| and, respectively

+% \subsection{Captions}
+%
+% There are two ways to add captions to (\pkgname{keyvaltable}-) tables:
+% The first way is to enclose the table in a |table| environment. This
+% is particularly suit for tables that do not span multiple pages, such
+% as those produced through the |onepage| shape (or |tabular|,
+% |tabularx|, and |tabu| -- see \cref{sec:AltTabEnv}).
+%
+% \begin{LTXexample}[morepreset=\RecipePreset,morekeywords={caption,label,ref}]

+% \caption{Cherries++}

+% \end{table}
+% Table~\ref{Cherries} shows the recipe.
+% \end{LTXexample}
+%
+% The second way to add captions is through the |caption| option of

+% \subsection{Tables from CSV Files (\pkgname{datatool} and \pkgname{csvsimple})}\label{sec:CSV}
+%
+% The \thispackage package itself does not offer its own functionality
+% for generating tables from CSV files. However, together with existing
+% CSV packages, table content can be sourced from CSV files.
+% The remainder of this section shows how this can be achieved by
+% example. The following CSV file serves as the data file in the
+% examples. We use the same |Recipe| table type as previously.
+%
+% \lstinputlisting[caption=recipes.csv]{recipes.csv}
+%
+% \paragraph{\pkgname{datatool}}
+% The package provides a variety of macros for loading and also
+% displaying CSV database content. The following shows how the macros
+% |\DTLloaddb| and |\DTLforeach*| can be used, together with
+% |\AddKeyValRow| and |\ShowKeyValTable|.
+% The example also shows how a simple filter can be applied to the rows
+% via |\DTLforeach*|.
+%
+% \begin{LTXexample}[morepreset=\RecipePreset,morekeywords={DTLloaddb,DTLforeach,expandonce}]
+% \usepackage{datatool}
+% \DTLloaddb{recipes}{recipes.csv}
+% \DTLforeach*[\equal{\Id}{snowman}]{recipes}
+% {\Id=id,
+% \Amount=amount,\Ingr=ingredient,\Step=step}
+% {\AddKeyValRow{Recipe}[expandonce]{
+% amount=\Amount,ingredient=\Ingr,step=\Step}}
+% \ShowKeyValTable{Recipe}
+% \end{LTXexample}
+%
+% Two aspects shall be noted.
+% Firstly, we use |\AddKeyValRow| rather than |KeyValTable|,
+% because |\DTLforeach*| interferes with how |KeyValTable| constructs
+% its rows and yields "misplaced |\noalign|" errors. We do not use
+% |\CollectRow| here, because it requires two runs and we do not need
+% the feature to show the table before the rows are specified.
+% Secondly, we use the row option |expandonce| to ensure that the macros
+% |\Amount|, |\Ingr|, and |\Step| are expanded (i.e., replaced by their
+% values). Without this option, all rows would only carry the three
+% macros and display the value that these macros have at the time of the
+% |\ShowKeyValTable|.
+%
+% \NiceDescribeKeys{2}
+% {expandonce}{vals={true,false}, init=false, def=true}
+% {expand}{vals={true,false}, init=false, def=true}
+% These row options can be used when programmatically constructing the
+% rows of a table, particularly with |KeyValTableContent| and
+% |\CollectRow|.
+% The |expandonce| option expands all the cell values
+% given to a row (default values not included) exactly once before
+% including it in the respective row.
+% The |expand| option fully expands the cell values, in |protect|'ed
+% mode (i.e., robust commands are not expanded).
+%
+%
+% \paragraph{\pkgname{csvsimple}}
+% For the sake of our example, using this package is very similar to
+% using \pkgname{datatool}.
+%
+% \begin{LTXexample}[morepreset=\RecipePreset,morekeywords={csvreader,expand}]
+% \usepackage{csvsimple}
+% \csvreader[head to column names,
+% filter equal={\id}{cherries}]{recipes.csv}{}
+% {\AddKeyValRow{Recipe}[expand]{
+% amount=\amount,ingredient=\ingredient,
+% step=\step}}
+% \ShowKeyValTable{Recipe}
+% \end{LTXexample}
+%
+% Two differences are noteworthy here:
+% First, we can avoid specifying macro names for the columns through the
+% |head to column names|, which uses the column names as macro names.
+% Second, we have to use the |expand| option rather than |expandonce|
+% here, because \pkgname{csvsimple} apparently does not directly store
+% the column value in the respective macro.
