|
|
% standard LaTeX's \multicolumn
|
|
% 1. does not allow verbatim contents,
|
|
% 2. interacts very poorly with tabulary.
|
|
%
|
|
% It is needed to write own macros for Sphinx: to allow code-blocks in merged
|
|
% cells rendered by tabular/longtable, and to allow multi-column cells with
|
|
% paragraphs to be taken into account sanely by tabulary algorithm for column
|
|
% widths.
|
|
%
|
|
% This requires quite a bit of hacking. First, in Sphinx, the multi-column
|
|
% contents will *always* be wrapped in a varwidth environment. The issue
|
|
% becomes to pass it the correct target width. We must trick tabulary into
|
|
% believing the multicolumn is simply separate columns, else tabulary does not
|
|
% incorporate the contents in its algorithm. But then we must clear the
|
|
% vertical rules...
|
|
%
|
|
% configuration of tabulary
|
|
\setlength{\tymin}{3\fontcharwd\font`0 }% minimal width of "squeezed" columns
|
|
\setlength{\tymax}{10000pt}% allow enough room for paragraphs to "compete"
|
|
% we need access to tabulary's final computed width. \@tempdima is too volatile
|
|
% to hope it has kept tabulary's value when \sphinxcolwidth needs it.

|
|
% next hack is needed only if user has set latex_use_latex_multicolumn to True:
|
|
% it fixes tabulary's bug with \multicolumn defined "short" in first pass. (if
|
|
% upstream tabulary adds a \long, our extra one causes no harm)

|
|
%
|
|
% TN. 1: as \omit is never executed, Sphinx multicolumn does not need to worry
|
|
% like standard multicolumn about |l| vs l|. On the other hand it assumes
|
|
% columns are separated by a | ... (if not it will add extraneous
|
|
% \arrayrulewidth space for each column separation in its estimate of available
|
|
% width).
|
|
%
|
|
% TN. 1b: as Sphinx multicolumn uses neither \omit nor \span, it can not
|
|
% (easily) get rid of extra macros from >{...} or <{...} between columns. At
|
|
% least, it has been made compatible with colortbl's \columncolor.
|
|
%
|
|
% TN. 2: tabulary's second pass is handled like tabular/longtable's single
|
|
% pass, with the difference that we hacked \TY@final to set in
|
|
% \sphinx@TY@tablewidth the final target width as computed by tabulary. This is
|
|
% needed only to handle columns with a "horizontal" specifier: "p" type columns
|
|
% (inclusive of tabulary's LJRC) holds the target column width in the
|
|
% \linewidth dimension.
|
|
%
|
|
% TN. 3: use of \begin{sphinxmulticolumn}...\end{sphinxmulticolumn} mark-up
|
|
% would need some hacking around the fact that groups can not span across table
|
|
% cells (the code does inserts & tokens, see TN1b). It was decided to keep it
|
|
% simple with \sphinxstartmulticolumn...\sphinxstopmulticolumn.
|
|
%
|
|
% MEMO about nesting: if sphinxmulticolumn is encountered in a nested tabular
|
|
% inside a tabulary it will think to be at top level in the tabulary. But
|
|
% Sphinx generates no nested tables, and if some LaTeX macro uses internally a
|
|
% tabular this will not have a \sphinxstartmulticolumn within it!

% bad for paragraph content. 2016 version has = specifier but it

% in the asked-for number of rows.

% 5. colour panels (either from \rowcolor or \columncolor) will hide

|
% the bottom part of multirow text, hence manual tuning is needed
|

% to put the multirow insertion at the _bottom_.
|
|
%
|

% The Sphinx solution consists in always having contents wrapped
