% \subsection{Column separation (colsep) and cell background}
% In-row decorations are the vertical borders between the cells
% and also the background color of the cells.
% \begin{macro}{\cals@cs@outOne}
% Typesets the background and the left border of a cell.
% Decorations have zero depth and undefined height.
% Parameters:
% \begin{enumerate}
% \item Width of the cell. The use of |\relax| avoids typesetting
% the cell itself, which is used when creating the right frame
% of a table.
% \item Width of the border. 0pt is no border.
% \item Color of the background. Empty macro is no color.
% \end{enumerate}
% If some arguments are undefined (through |\relax|), global
% variables are used: |\cals@bgcolor| and |\cals@cs@width|.
%
% Corrupts |dimen0|.
% \begin{macrocode}
\newcommand\cals@cs@outOne[3]{%
% \end{macrocode}
% Create the full-width background
% \begin{macrocode}
\ifx \relax#1%
\else
\cals@withColorII\cals@bgcolor{#3}\iftrue
\textcolor{\cals@color}{\vrule depth0pt width#1 }%
\hskip -#1\relax
\fi
\fi
% \end{macrocode}
% The border. I feel that overprinting the background is good,
% but I don't know why I think so.
% \begin{macrocode}
\cals@withWidthII\cals@cs@width{#2}\iftrue
\cals@halfWidthToDimen0 \cals@width %
\hskip -\dimen0 %
\vrule depth0pt width\cals@width\relax
\hskip -\dimen0 %
\fi
% \end{macrocode}
% We will need the actual width of the left border in
% a grand-grand-...-caller, when constructing a rowsep specification.
% \begin{macrocode}
\let\cals@lastLeftWidth=\cals@width
% \end{macrocode}
% Add width to skip to the next cell.
% \begin{macrocode}
\ifx \relax#1\else \hskip#1 \fi
}
% \end{macrocode}
% \end{macro}
% \begin{macro}{\cals@current@cs}
% The box to store column separation.
% \begin{macrocode}
\newbox\cals@current@cs
% \end{macrocode}
% \end{macro}
% \begin{macro}{\cals@csrow@begin}
% \begin{macro}{\cals@csrow@nextcell}
% \begin{macro}{\cals@csrow@end}
% Constructs an hbox with colsep decorations. Call to the begin-macro
% re-initializes |\cals@current@cs| and makes that the left table frame border
% is of the correct width. The end-macro creates the right border for
% the right table frame. The most work is performed in the nextcell-macro.
% Arguments:
% \begin{enumerate}
% \item Width of the cell
% \item Width of the left border
% \item Width of the right border, \emph{must be a macro name}
% \item Background color of the cell
% \end{enumerate}
% For the special conditions (|\relax|, 0pt, empty name) see
% the description of |\cals@cs@outOne|.
% The right border is not typeset immediately. Instead, it is saved
% to |\cals@lastWidth| (as |\relax| if no overrides)
% and is handled by the next call to |nextcell|.
% \begin{macrocode}
\newcommand\cals@csrow@begin{%
\setbox\cals@current@cs=\box\voidb@x %
\let\cals@lastWidth=\relax}
\newcommand\cals@csrow@nextcell[4]{%
% \end{macrocode}
% For the first cell, temporarily re-define the default border width
% to the frame border. Macro |\next| will restore it back.
% \begin{macrocode}
\ifvoid\cals@current@cs
\toks0=\expandafter{\cals@cs@width}%
\def\next{\edef\cals@cs@width{\the\toks0}}%
\edef\cals@cs@width{\cals@framecs@width}%
\else \let\next=\relax \fi
% \end{macrocode}
% Create the decorations, remember the right border.
% Restore the value |lastLeftWidth| after the end of the hbox-group.
% \begin{macrocode}
\cals@maxWidth\cals@lastWidth{#2}%
\setbox\cals@current@cs=\hbox{\unhbox\cals@current@cs
\cals@cs@outOne{#1}\cals@width{#4}%
\global\let\cals@tmp=\cals@lastLeftWidth}%
\let\cals@lastLeftWidth=\cals@tmp
\let\cals@lastWidth=#3%
% \end{macrocode}
% Restore the old value of the default border width.
% \begin{macrocode}
\next}
% \end{macrocode}
% User-specified width (initially by |borderR|, now located in
% |lastWidth|) must override the frame width.
% \begin{macrocode}
\newcommand\cals@csrow@end{%
\ifx \relax\cals@lastWidth
\let\cals@width=\cals@framecs@width
\else
\let\cals@width=\cals@lastWidth
\fi
\cals@csrow@nextcell\relax\cals@width\relax\relax}
% \end{macrocode}
% \end{macro}
% \end{macro}
