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. \newdimen\sphinx@TY@tablewidth \def\tabulary{% \def\TY@final{\sphinx@TY@tablewidth\@tempdima\tabular}% \let\endTY@final\endtabular \TY@tabular}% % 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.

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! % \def\sphinxstartmulticolumn{% \ifx\equation$% $ tabulary's first pass \expandafter\sphinx@TYI@start@multicolumn \else % either not tabulary or tabulary's second pass \expandafter\sphinx@start@multicolumn \fi }% \def\sphinxstopmulticolumn{% \ifx\equation$% $ tabulary's first pass \expandafter\sphinx@TYI@stop@multicolumn \else % either not tabulary or tabulary's second pass \ignorespaces \fi }% \def\sphinx@TYI@start@multicolumn#1{% % use \gdef always to avoid stack space build up \gdef\sphinx@tempa{#1}\begingroup\setbox\z@\hbox\bgroup }% \def\sphinx@TYI@stop@multicolumn{\egroup % varwidth was used with \tymax \xdef\sphinx@tempb{\the\dimexpr\wd\z@/\sphinx@tempa}% per column width \endgroup \expandafter\sphinx@TYI@multispan\expandafter{\sphinx@tempa}% }% \def\sphinx@TYI@multispan #1{% \kern\sphinx@tempb\ignorespaces % the per column occupied width \ifnum#1>\@ne % repeat, taking into account subtleties of TeX's & ... \expandafter\sphinx@TYI@multispan@next\expandafter{\the\numexpr#1-\@ne\expandafter}% \fi }% \def\sphinx@TYI@multispan@next{&\relax\sphinx@TYI@multispan}% % % Now the branch handling either the second pass of tabulary or the single pass % of tabular/longtable.

The difficulty is that to get the said width, the % template must be inserted (other hacks would be horribly complicated except % if we rewrote crucial parts of LaTeX's \@array !) and we can not do % \omit\span like standard \multicolumn's easy approach. Thus we must cancel % the \vrule separators. Also, perhaps the column specifier is of the l, c, r % type, then we attempt an ad hoc rescue to give varwidth a reasonable target % width. \def\sphinx@start@multicolumn#1{% \gdef\sphinx@multiwidth{0pt}\gdef\sphinx@tempa{#1}\sphinx@multispan{#1}% }% \def\sphinx@multispan #1{% \ifnum#1=\@ne\expandafter\sphinx@multispan@end \else\expandafter\sphinx@multispan@next \fi {#1}% }% \def\sphinx@multispan@next #1{% % trick to recognize L, C, R, J or p, m, b type columns \ifdim\baselineskip>\z@ \gdef\sphinx@tempb{\linewidth}% \else % if in an l, r, c type column, try and hope for the best \xdef\sphinx@tempb{\the\dimexpr(\ifx\TY@final\@undefined\linewidth\else \sphinx@TY@tablewidth\fi-\arrayrulewidth)/\sphinx@tempa -\tw@\tabcolsep-\arrayrulewidth\relax}% \fi \noindent\kern\sphinx@tempb\relax \xdef\sphinx@multiwidth {\the\dimexpr\sphinx@multiwidth+\sphinx@tempb+\tw@\tabcolsep+\arrayrulewidth}% % hack the \vline and the colortbl macros \sphinx@hack@vline\sphinx@hack@CT&\relax % repeat \expandafter\sphinx@multispan\expandafter{\the\numexpr#1-\@ne}% }% % packages like colortbl add group levels, we need to "climb back up" to be % able to hack the \vline and also the colortbl inserted tokens.

The needed mark-up is done % by LaTeX writer, which has its own id for the merged cells. % % The colour issue is solved by clearing colour panels in all cells, % whether or not the multirow is single-column or multi-column. % % In passing we obtain baseline alignements across rows (only if % \arraylinestretch is 1, as LaTeX's does not obey \arraylinestretch in "p" % multi-line contents, only first and last line...) % % TODO: examine the situation with \arraylinestretch > 1.
