% \maketitle
% \begin{abstract}\noindent
% The \texttt{ctable} package provides a \texttt{ctable}
% command for the typesetting of table and figure floats. You will
% not need to type the usual nested begin...end sequences, as
% \texttt{ctable} is a command, not an environment. \texttt{ctable}
% has only 4 arguments, but the optional first one may hold many
% \textsl{key=value} pairs and makes \texttt{ctable} very flexible
% and extensible. It uses Simon Fear's \REF{booktabs} package for
% better vertical spacing around horizontal rules and it provides
% facilities for making table footnotes.
% \end{abstract}
%
% \section{Purpose} The |ctable| package lets you easily typeset
% captioned table and figure floats with optional
% footnotes. Both caption and footnotes will normally be forced within the
% width of the table.
% If the width of the table is specified, then \REF{tabularx} will be used
% to typeset it, and one or more |X| column specifiers should be specified.
% Otherwise tabular will be used.
%
% This package defines the commands |\ctable|,
% |\tnote| and |\tmark|, as well as four |\tabularnewline| generating
% commands. The latter generate reasonable amounts of whitespace
% around horizontal rules and are also useful for tabulars outside
% this package.
%
% Since the |ctable| package imports the \REF{array} and \REF{booktabs}
% packages, all commands from those packages are available as well.
%
% Note that, in line with the comments that Simon Fear made
% describing his \REF{booktabs} package, vertical rules for column
% separation can be produced with |\ctable|, but no provisions are
% made to have them make contact with horizontal rules.
%
% \section{Usage}
% \DescribeMacro{\ctable}
% |\ctable| is called with 4 parameters, of which the first is optional: \\
%
% |\ctable[options]       % key=value,...|\\
% |       {coldefs}       % for \begin{tabular}|\\
% |       {foottable}     % zero or more \tnote commands (see below)|\\
% |       {table rows}    % rows for the table|\\
%
% Options are given as key=value pairs, separated by comma's.
% Extra comma's, including one behind the last pair, don't hurt.
% Arguments to option should be put between braces if they contain
% comma's or equals signs.
% Currently the following option keys have been defined:
% \\[2ex]
% \begin{tabularx}{\hsize}{@{}lX@{}}
% |caption={...}|& table caption; the braces are needed only if your
%                   caption contains a comma or an equals sign.\NN[1ex]
%
% |cap={...}|    & for a short caption to go to the |\listoftables|.
%                  Without the |cap| option, the full caption will go
%                  into the |\listoftables|. If |cap| is given an empty 
%                  value, no entry in the |\listoftables| will be made.
%                  This may be useful, for example, with the |continued|
%                  option.\NN[1ex]
%
% |continued[=...]| & if used, the table will be numbered the same as the
%                  previous table. If used without an argument, the caption
%                  will be suffixed with ` (continued)', if used with an
%                  argument, the suffix will be the argument.\NN[1ex]
%
% |captionskip=...| & moves the caption relative to the table;
%                  the default is |0ex|, which puts captions at
%                  their default \LaTeX\ positions: a top
%                  caption's baseline at |1ex| above the top rule
%                  position of the table and a bottom caption's
%                  baseline at |4ex| below the bottom rule
%                  position.\NN[1ex]
%
% |mincapwidth=...| & sets the minimum width of the float. Without
%                  this option, the width is set to that of the
%                  tabular, and the caption and footnotes are
%                  typeset within that width. This may be a
%                  problem with very narrow tables; |mincapwidth|
%                  can then be used to give the float a minimum
%                  width. The tabular will be centered in it.\NN[1ex]
%
% |doinside=...| & command to be run inside, just before the tabular
%                  or tabularx environment. You can use this, for example, 
%                  for the adjustment of the font size with |\small|.\NN[1ex]
%
% |pos=...|      & float position, default: |tbp|.\NN[1ex]
%
% |label=...|    & for |\label|\NN[1ex]
%
% |width=...|    & \REF{tabularx} will be used to typeset the table at the
%                  specified width\,---\,one or more |X| column
%                  specifiers must be provided.\NN[1ex]
%
% |maxwidth=...| & like the \textsl{width} option, but any |X| column
%                  specifiers will be replaced with |l| if the resulting
%                  table width would thus stay within the specified
%                  maximum width. This is especially useful where the
%                  \LaTeX\ source is generated by a script.\NN[1ex]
%
% |center|       & center the table in the available text width; this is
%                  the default.\NN[1ex]
%
% |left|         & left align the table in the available text width.\NN[1ex]
%
% |right|        & right align the table in the available text width.\NN[1ex]
%
% |figure|       & produce a figure float instead of a table float.\NN[1ex]
%
% |botcap|       & put the caption at the bottom of the float instead
%                  of on top of it.\NN[1ex]
%
% |sideways|     & rotate table or figure by 90 degrees anticlockwise
%                  and put it on a separate page. With the twoside option
%                  for the standard \LaTeX\ document classes, rotation
%                  will be -90 on even pages. If you use this option,
%                  the |pos| option is not allowed.\NN[1ex]
%
% |star|         & use the starred versions of the |table| and |figure|
%                  environments, which place the float over two columns
%                  when the |twocolumn| option or the |\twocolumn|
%                  command is active.\NN[1ex]
%
% |nosuper|      & in the footnote table, typeset footnote markers on
%                  the line, instead of superscripted.\NN[1ex]
%
% |notespar|     & typeset footnotes in a parapgraph instead of in a table.\NN[1ex]
%
% |framerule=...|& draw a frame around the table with the given rule
%                  thickness. The default is |0pt|, so that no frame
%                  will be seen.\NN[1ex]
%
% |framesep=...| & set the distance between the frame and the table
%                 to the given dimension. The default is |0pt|.\NN[1ex]
%
% |framefg=|\slshape r g b & set the foreground color of the frame (the
%                 rule color) to the given triplet of
%                 \textsl{rgb}-values. The values should be numbers
%                 between 0 and 1. The default is |0 0 0| (black).\NN[1ex]
%
% |framebg=|\slshape r g b & set the background color of the frame (the
%                 color inside the frame) to the given triplet of
%                 \textsl{rgb}-values. The values should be numbers
%                 between 0 and 1. The default is |1 1 1| (white).\NN[1ex]
% \end{tabularx}
% \\[2ex]
% The footnotes are placed under the table, without a rule.
% You therefore probably will want to use the |\LL| (last line)
% command if you use footnotes.
% \DescribeMacro{\tnote}
% |\tnote[label]{footnote text}| places {\footnotesize
% \textsuperscript{\normalfont\textit{label}}\,footnote text}
% under the table.
% Can only be used in the foottable parameter described above. The
% label is optional, the default label is a single $a$. For more
% detailed control, you can also replace this command with something
% like |labeltext&footnotetext\NN|.
% \par
% \DescribeMacro{\tmark}
% |\tmark[label]| this command places the superscripted label in the
% table. It is equivalent with |$^{label}$|.
% The label is optional, the default label is a single $a$.
% \par
% The newline generating commands are a combination of
% |\tabularnewline| and zero or one of \REF{booktabs} |\toprule|,
% |\midrule| or |\bottomrule|. These combinations have been made, and
% short names have been defined, because source texts for complex
% tables often become very crowded:
% \par
% \DescribeMacro{\NN} Normal Newline, generates just a normal new line.
% An optional dimen parameter inserts extra vertical space under the
% line.
% \par
% \DescribeMacro{\FL} First Line, generates a new line and a thick
% rule with some extra space under it.
% An optional dimen parameter sets the line width; the default is 0.08em.
% \par
% \DescribeMacro{\ML} Middle Line: generates a new line and a thin
% rule with some extra space over and under it.
% An optional dimen parameter sets the line width; the default is 0.05em.
% \par
% \DescribeMacro{\LL} Last Line:  generates a new line and a thick
% rule with some extra space over it.
% An optional dimen parameter sets the line width; the default is 0.08em.
% \par
% These macros can be used outside |\ctable| constructs.
% \par
% Finally, for completeness, here are some of \REF{booktabs}' commands
% that may be useful:
% \par
% \DescribeMacro{\toprule} |\toprule[<wd>]|
% where |<wd>| is the optional thinkness of the rule.
% \par
% \DescribeMacro{\midrule} |\midrule[<wd>]|.
% \par
% \DescribeMacro{\bottomrule} |\bottomrule[<wd>]|.
% \par
% \DescribeMacro{\cmidrule} |\cmidrule[<wd>](<trim>){a-b}|
% where |<trim>| can be |r|, |l|, or |rl|
% and the rule is drawn over columns |a| through |b|.
% \par
% \DescribeMacro{\morecmidrules} |\morecmidrules|
% must be used to separate two successive cmidrules.
% \par
% \DescribeMacro{\addlinespace} |\addlinespace[<wd>]|
% inserts extra space between rows.
% \par
% \DescribeMacro{\specialrule}
% |\specialrule{<wd>}{<abovespace>}{<belowspace>}|.
% \par
% See the \REF{booktabs} documentation for details.

% \subsection{The width and maxwidth options}
% When \LaTeX-sources containing tables are generated automatically by a
% script, it is often not known in advance what the maximum size of an
% |l|~column will be. A good solution for this is to use an |X|~specifier,
% typesetteing the table at the text width with the \REF{tabularx} package.
% However, this will result in too much white space in cases where the
% column contains small texts only. This problem can be solved by using
% the maxwidth option instead of the width option. The |X|~specifiers will
% then be replaced with |l| as long as the width of the resulting table
% stays with the specified maximum width.
%
% \section{Examples}
% Table~\ref{nowidth} is an example taken from the related package
% \REF{threeparttable} by Donald Arseneau, with an extra footnote.
% It was typeset with:
% \color{vbgreen}

%
% Figures, even single ones, are always put in tabular cells. This is not
% particularly handy for single pictures, but it eases the construction of
% arrays of pictures, including sub-captions, delineation, and spacing. For a
% small example, which also shows how you can simplify the construction of
% figure arrays, see subsection~\ref{figureexample} on
% page~\pageref{figureexample}.
%
% \section{Option examples}
% In the following, small examples will be shown illustrating the effect of
% options. In the left column the relevant part of the source is shown, in the
% right column you see the result. In most cases you see a standard example on a
% light yellow background, followed by one or more variations on a light blue
% background. Where necessary, the example will show boxes to indicate the page
% and the text body.
%
% \subsection{\ttfamily\bfseries center, left, right}
% These options align the float in the page; the default is |center|:
% \medskip\\
% \ROW{Y}{s02k}{02k}
% \ROW{B}{s02l}{02l}
% \ROW{B}{s02m}{02m}
% 
% \subsection{\ttfamily\bfseries nosuper}
% Footnote markers in |ctable| are typeset superscripted by default. Use the
% |nosuper| option to place them on the base line:
% \medskip\\
% \ROW{Y}{s07a}{07a}
% \ROW{B}{s07b}{07b}
% 
% \subsection{\ttfamily\bfseries notespar}
% Footnotes in |ctable| are typeset in a paragraph, instead of a table: 
% \medskip\\
% \ROW{Y}{s12a}{12a}
% \ROW{B}{s12b}{12b}
% 
% \subsection{\ttfamily\bfseries continued}
% The |continued| option suffixes the caption with ` (continued)', and lowers the table
% number by one, so that it obtains the same number as the previous table.
% This option can be given an argument to replace the default suffix:
% \medskip\\
% \ROW{Y}{s13a}{13a}
% \ROW{B}{s13b}{13b}
% \ROW{B}{s13c}{13c}
% 
% \subsection{\ttfamily\bfseries mincapwidth}
% |ctable| forces caption and footnotes to stay within the width of the table.
% Sometimes, however, tables are so narrow, that this is not really what you want.
% In such cases, use the |mincapwidth| option to give caption and footnotes some
% extra room:
% \medskip\\
% \ROW{Y}{s05a}{05a}
% \ROW{B}{s05b}{05b}
% \medskip
% You can set |mincapwidth| to a large value, say |\hsize|, if you want a one-line
% caption. Note, however, that this may influence the horizontal positioning of
% the table: values larger than |\hsize| will move a centered table out of the
% center, a value of |\hsize| will prevent the |left| and |right| options to do
% their work, because the table is already captured between the left and right
% margins.
% 
% \subsection{\ttfamily\bfseries maxwidth}
% When \LaTeX-sources containing tables are generated automatically by a
% script, it is often not known in advance what the maximum size of an |l|
% column will be. A good solution for this is to use an |X| specifier,
% typesetting the table at the text width with the \REF{tabularx} package.
% However, this will result in too much white space in cases where the
% column contains small texts only. This problem can be solved by using
% the maxwidth option instead of the width option. The |X| specifiers will
% then be replaced with |l| as long as the width of the resulting table
% stays with the specified maximum width.
% \medskip\\
% \ROW{Y}{s06a}{06a}
% \ROW{B}{s06b}{06b}
% 
% \newpage
% \subsection{\ttfamily\bfseries framerule}
% The following examples show the use of frames and backgrounds. Every table
% is typeset by |ctable| with a frame around it, but the frame is, by default,
% drawn with a zero width line, and is therefore invisible. You can make it
% visible by either changing the linewidth to a positive value or by giving it a
% background color, which will be used to fill the frame.
% 
% Here is a simple table without a frame, followed by one with a red, |1pt| thick
% frame:
% \medskip\\
% \ROW{Y}{s08a}{08a}
% \ROW{B}{s08b}{08b}
% \medskip
% As you see, the frame fits closely to the first (|\FL|) and last (|\LL|) table
% lines. This can be a reason to either remove those lines, or to introduce some
% whitespace between the frame and the table with the |framesep| option:
% \medskip\\
% \ROW{B}{s09b}{09b}
% \medskip
% And finally, we could also frame the table by giving it a, say, yellow backgound
% instead of a red frame line, or even do both:
% \medskip\\
% \ROW{Y}{s10a}{10a}
% \ROW{B}{s10b}{10b}
% 
% \newpage
% \subsection{\ttfamily\bfseries captionskip}
% The distance between a top caption and the table is \texttt{2ex},
% but it can be varied with \texttt{captionskip}:
% \medskip\\
% \ROW{Y}{s03a}{03a}
% \ROW{B}{s03b}{03b}
% \medskip
% This works for bottom caption, too:
% \medskip\\

% \subsection{\ttfamily\bfseries figure, botcap}\label{figureexample}
% By default, |ctable| generates a table float, but with the |figure| option, a
% figure float is generated instead. The caption stays on top, so if you are
% accustomed to have bottom caption for your figures, you will probably also need
% the |botcap| option:
% \medskip\\
% \ROW{Y}{s01a}{01a}

% \newpage
% \subsection{\ttfamily\bfseries sideways}
% The |sideways| option creates a landscape table with its head pointing at the
% spine\,---\,when the documentclass' twoside option has been used, that is. The
% following examples show the effect of the |sideways| option, first on page one,
% then on page 2. Note that the |caption| option has not been used, so no caption
% appears:
% \medskip\\
