+# lutabulartools
+
+This LuaLaTeX package offers some useful macros for tabular matter. The `\MC` command it provides allows one to specify a multi-row and or multi-column cell with minimal syntax. The package loads `booktabs` and adds a gray midrule, and allows a user to specify multiple `\cmidrules` with one command.

+    2021-09-24, Kale Ewasiuk, \url{kalekje@gmail.com}
+
+lutabulartools is a package that contains a few useful macros to help with tables.
+Most functions require LuaLaTeX. The following packages are loaded:
+{\tt
+{booktabs},
+{multirow},
+{makecell},
+{xparse},
+{array},
+{xcolor},
+{colortbl},
+{luacode},
+{penlight},
+}
+
+\section{\texttt{\textbackslash MC} -- Magic Cell}
+\texttt{\textbackslash MC} (magic cell) combines the facilities of
+\CMD{multirow} and \CMD{multicolumn} from the \texttt{multirow} package, and \CMD{makcell} from the titular package.
+With the help of LuaLaTeX, it takes an easy-to-use cell specification and employs said commands as required.
+Here is the usage:
+
+\texttt{\textbackslash MC * [cell spec] <cell format> (override multicolumn col) \{contents\} }
+
+\PARA{*}This will wrap the entire command in \{\}. This is necessary for \texttt{siunitx} single-column width columns.
+However, the \tMC\  command attempts to detect this automatically.
+
+\PARA{[cell spec]}%
+Any letters placed in this argument are used for cell alignment.
+You can use one of three: \ttt{t}, \ttt{m}, \ttt{b} for top, middle, bottom (vertical alignment),
+or \ttt{l}, \ttt{c}, \ttt{r} for horizontal alignment.
+By default, \tMC\   will try to autodetect the horizontal alignment based on the current column.
+If it can't, it will be left-aligned.
+The default vertical alginment is top.
+
+This argument can also contain two integers, separated by a comma (if two are used).
+\ttt{C,R}, \ttt{C}, or \ttt{,R} are a valid inputs,
+where R=rows (int), and C=columns, (int).
+If you want a 1 column wide, multirow cell,
+you can pass \ttt{,R}. These numbers can be negative.
+If no spec is passed, (argument empty), \tMC\
+acts like a \texttt{makecell}.
+Additionally, you can pass \ttt{+} in place of C (number of columns wide),
+and it will make the cell width fill until the end of the current row.
+
+Examples:\\
+\ttt{\textbackslash MC[2,2]} means two columns wide, two rows tall.\\
+\ttt{\textbackslash MC[2,1]} or \ttt{\textbackslash MC[2]} or  means two columns wide, one row tall.\\
+\ttt{\textbackslash MC[1,2]} or \ttt{\textbackslash MC[,2]} means one column wide, two rows tall.\\
+In any of these examples, you can place the alignment letters anywhere.
+
+
+\PARA{(override}%
+You may want to adjust the column specification of a multicolumn  cell,\\
+\PARA{multicolumn)}for example, using
+\texttt{@\{\}c@\{\}} to remove padding between the cell.
+
+\PARA{<cell format>}%
+You can place formatting like \CMD{bfseries} here.
+
+Here's an example.
+
+\Example{
+\begin{tabular}{| c | c | c | c | c | c |}\toprule
+ \MC[2,2cm]<\tt>{2,2cm}   & \MC[2r]<\tt>{2r} & 5 & \MC[,2b]<\tt>{,2b}\\
+   &   & 3 & 4 & 5 & \\\midrule
+ 1 & 2 & \MC[2l](@{}l)<\tt>{2l (\@\{\}l)} & 5 & 6666\\\cmidrule{3-4}
+ 1 & \MC[+r]<\tt>{+r}  \\
+  \\
+ 1 & 2 & 3 & 4 & 5 & \MC[,-2]<\tt>{,\\-2}\\
+\end{tabular}
+}
+
+%%% https://tex.stackexchange.com/questions/287346/width-of-column-after-multicolumn-header
+
+%\textbackslash MC[<spec>]{<contents}
+
+\subsection{Notes}
+This package redefines the {\tt tabular} and {\tt tabular*| environments.
+It uses Lua pattern matching to parse the column specification of the table to know how many columns there are,
+and what the current column type is. If you have defined a column that creates many, it will not work.
+This will be worked out in later package revisions.
+%But, to know how many columns there are you, you will have
+%either have to manually set todo the lua variable before the table, or,
+%in the last column of the first row, \texttt{get\_tab\_colnum ()}.
+%The above Lua function can be used to get the current column number.
+%You will also remove the ability for this package to know what the current column spec is
+
+
+
+\section{Some additional rules}
+This package also redefines the \texttt{booktabs} midrules.\\
+\PARA{\textbackslash gmidrule}is a full gray midrule.\\
+By taking advantage of knowing how many columns there are (if you chose to redefine \texttt{tabular}),
+you can specify individual column numbers (for a one column wide rule),
+or reference with respect to the last column (blank, \texttt{+1}, \texttt{+0}, or \texttt{+} means last column,
+\texttt{+2} means second last column, for example)
+or omit the last number.\\
+\PARA{\textbackslash cmidrule}is a single partial rule, with the above features\\
+\PARA{\textbackslash gcmidrule}is a single partial gray rule, with the above features\\
+You can add multiple \ttt{cmidrule}'s with the \texttt{(g)cmidrules} command. Separate with a comma.
+You can apply global trimming of the rules with the \ttt{()} optional argument, and then
+override it for a specific rule by placing \ttt{r} or \ttt{l} with the span specification.\\
+\PARA{\textbackslash gcmidrules}Can produce multiple, light gray partial rules\\
+\PARA{\textbackslash cmidrules}Can produce multiple black partial rules.\\
+Here's an example:
+
+\Example{
+\begin{tabular}{c c c c c c}\toprule
+ 1 & 2 & 3 & 4 & 5 & 6\\ \cmidrule{+1}  % rule on last column
+ 1 & 2 & 3 & 4 & 5 & 6\\ \cmidrules{1,3-+3,+} % rule on first col, third to third last col, and last col
+ 1 & 2 & 3 & 4 & 5 & 6\\ \cmidrules{1,3-+3rl,+} % same as above, but trim middle
+ 1 & 2 & 3 & 4 & 5 & 6\\ \cmidrules(l){1,r3-+3,+1}% trim left for all, but only trim right for middle rule
+\end{tabular}
+}
+
+\subsection{Midrule every X\textsuperscript{th} row}
+
+\PARA{\textbackslash midruleX}%
+With this command, you can place a rule
+every X rows.
+You can change the step size and what kind of midrule you prefer.
+\begin{verbatim}
+\def\midruleXstep{5}
+\def\midruleXrule{\gmidrule}
+\end{verbatim}
+
+
+Usage: Insert midrulex at the end of each row in the column spec. Before you want counting to beg
+\begin{verbatim}
+
+\def\midruleXstep{4}
+\def\midruleXrule{\cmidrules{1,3-4}}
+\begin{tabular}{rclc@{\midruleX}}  % inject midrule
+\toprule
+Num  & . & . & .  \\\midrule\resetmidruleX  % reset to 0
+1    & & &  \\
+2    & & &  \\
+3    & & &  \\
+4    & & &  \\
+5    & & &  \\
+6    & & &  \\
+7    & & &  \\
+8    & & &  \\
+9    & & &  \\
+10   & & &  \\
+11   & & &  \\\resetmidruleX % dont want a bottom rule
+12   & & &  \\
+\bottomrule
+\end{tabular}
+\end{verbatim}
+
+    will produce
+
+\def\midruleXstep{4}
+\def\midruleXrule{\cmidrules{1,3-4}}
+\begin{tabular}{rclc@{\midruleX}}  % inject midrule
+\toprule
+Num  & . & . & .  \\\midrule\resetmidruleX  % reset to 0
