+\RequirePackage{tabulary}
+% tabulary has a bug with its re-definition of \multicolumn in its first pass
+% which is not \long. But now Sphinx does not use LaTeX's \multicolumn but its
+% own macro. Hence we don't even need to patch tabulary. See
+% sphinxpackagemulticell.sty
+% X or S (Sphinx) may have meanings if some table package is loaded hence
+% \X was chosen to avoid possibility of conflict
+\newcolumntype{\X}[2]{p{\dimexpr

+\newcolumntype{\Y}[1]{p{\dimexpr
+ #1\dimexpr\linewidth-\spx@arrayrulewidth\relax-\tw@\tabcolsep-\spx@arrayrulewidth\relax}}
+% \spx@arrayrulewidth is used internally and its meaning will be set according
+% to the table type; no extra user code should modify it. In particular any
+% \setlength{\spx@arrayrulewidth}{...} may break all of LaTeX... (really...)

+% NOTA BENE: since the multicolumn and multirow code was written Sphinx
+% decided to prefix non public internal macros by \spx@ and in fact all
+% such macros here should now be prefixed by \spx@table@, but doing the
+% update is delayed to later. (written at 5.3.0)
+
+%%%%%%%%%%%%%%%%%%%%%
+% --- MULTICOLUMN ---
+% 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.
+\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. (if
+% upstream tabulary adds a \long, our extra one causes no harm)
+\def\sphinx@tempa #1\def\multicolumn#2#3#4#5#6#7#8#9\sphinx@tempa
+ {\def\TY@tab{#1\long\def\multicolumn####1####2####3{\multispan####1\relax}#9}}%
+\expandafter\sphinx@tempa\TY@tab\sphinx@tempa
+%
+% 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).
+%
+% Update at 5.3.0: code uses \spx@arrayrulewidth which is kept in sync with the
+% table column specification (aka preamble):
+% - no | in preamble: \spx@arrayrulewidth -> \z@
+% - at least a | in the preamble: \spx@arrayrulewidth -> \arrayrulewidth
+% This is used for computation of merged cells widths. Mixed preambles using
+% at least a | but not using it for all columns (as can be obtained via the
+% tabularcolumns directive) may cause some merged cells contents to be slightly
+% shifted to the left as they assume merged columns are | separated where in
+% fact they perhaps are not.
+%
+% 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!
+%
+% 5.3.0 adds a check for multirow as single-row multi-column will allow a row
+% colour but multi-row multi-column should not.
+% Attention that this assumes \sphinxstartmulticolumn is always followed
+% in latex mark-up either by \sphinxmultirow or \begin (from \begin{varwidth}).

+% dimensions from the p columns either set-up by tabulary or by user p column
+% or Sphinx \X, \Y columns. 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

+% hacking around colour matters
+% Sphinx 1.6 comment:
+% It turns out \CT@row@color is not expanded contrarily to \CT@column@color
+% during LaTeX+colortbl preamble preparation, hence it would be possible for
+% \CT@setup to discard only the column color and choose to obey or not
+% row color and cell color. It would even be possible to propagate cell color
+% to row color for the duration of the Sphinx multicolumn... the (provisional?)
+% choice has been made to cancel the colortbl colours for the multicolumn
+% duration.
+% Sphinx 5.3.0 comment:
+% - colortbl has no mechanism to disable colour background in a given cell:
+% \cellcolor triggers one more \color, but has no possibility to revert
+% a previously emitted \color, only to override it via an additional \color
+% - prior to 5.3.0, Sphinx did not officially support colour in tables,
+% but it did have a mechanism to protect merged cells from being partly
+% covered by colour panels at various places. At 5.3.0 this mechanism
+% is relaxed a bit to allow row colour for a single-row merged cell.

+% --- MULTIROW ---
+% standard \multirow
+% 1. does not allow verbatim contents,
+% 2. does not allow blank lines in its argument,
+% 3. its * specifier means to typeset "horizontally" which is very
+% bad for paragraph content. 2016 version has = specifier but it
+% must be used with p type columns only, else results are bad,
+% 4. it requires manual intervention if the contents is too long to fit
+% 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
+% in a varwidth environment so that it makes sense to estimate how many
+% lines it will occupy, and then ensure by insertion of suitable struts
+% that the table rows have the needed height. 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.
+%
+% MEMO at 5.3.0: to allow a multirow cell in a single column to react to
+% \columncolor correctly, it seems only way is that the contents
+% are inserted by bottom cell (this is mentioned in multirow.sty doc, too).
+% Sphinx could at Python level "move" the contents to that cell. But the
+% mechanism used here via \sphinxtablestrut to enlarge rows to make room for
+% the contents if needed becomes more challenging yet, because \sphinxtablestrut
+% mark-up will be parsed by TeX *before* it sees the contents of the merged
+% cell.. So it seems the best way would be to actually store the contents into
+% some owned-by-Sphinx box storage which needs to be globally allocated to
+% that usage ; then we need multiple such boxes, say at least 5 to cover
+% 99% or use case. Or perhaps some trick with storing in a \vbox and recovering
+% via some \vsplit but this becomes complicated... perhaps in future.
+%
+% In passing we obtain baseline alignements across rows (only if
+% \arraystretch is 1, as LaTeX's does not obey \arraystretch in "p"
+% multi-line contents, only first and last line...)
+%
+% TODO: examine the situation with \arraystretch > 1. The \extrarowheight
+% is hopeless for multirow anyhow, it makes baseline alignment strictly
+% impossible.

+% LaTeX's \cline has **strong** deficiencies
+% ******************************************
+% We work around them via an added \sphinxfixclines{number of columns} in the
+% table mark-up, and also extra mark-up \sphinxvlinecrossing{col no} for
+% crossings not contiguous to any cline. To fix the gap at left extremity of a
+% \cline, we redefine the core LaTeX \c@line because this avoids adjoining a
+% small square with potential PDF viewer anti-aliasing issues. We waited
+% after loading colortbl because it also redefines \c@line for it to obey the
+% colour set by \arrayrulecolor.
+% MEMO: booktabs package does *not* redefine \@cline so we are safe here.

+% Comments:
+%
+% If we had the information whether the previous column ended with a | or
+% not, we could decide what to do here. Alternatively the mark-up could
+% use either original \cline or the one modified as here depending on case.
+% One wonders why LaTeX does not provide itself the alternative as a
+% complement to \cline, to use on case by case basis.
+% Here we handle both at same time via using the \spx@arrayrulewidth which
+% will be \z@ if no | at all so will induce here nothing.
+%
+% As a result Sphinx basically supports well only tables having either all
+% columns |-separated, or no | at all, as it uses \spx@arrayrrulewidth in
+% all columns (here and in multicolumn code).
+%
+% We also considered a method not modifying \c@line but it requires too
+% much extra mark-up from Python LaTeX writer and/or extra LaTeX coding.

+%
+% - passing option "table" to xcolor also loads colortbl but we needed to
+% load color or xcolor prior to the handling of the options
+%
+% - the \rowcolors command from [table]{xcolor} has various problems:
+%
+% * it is rigid and does not out-of-the-box allow a more complex scheme
+% such as colorA+colorB+colorC+colorB+colorC+colorB+colorC... suitable to
+% distinguish a header row.
+%
+% * its code does not export the used colour, an information which we may
+% need for example to colourize the rule via \arrayrulecolor in the
+% appropriate manner, for example to colourize the booktabs induced vertical
+% whitespace to avoid gaps (if one wants to).
+%
+% * incompatibility with tabulary: the output depends on parity of total
+% number of rows!
+%
+% * problems with longtable: the caption will receive a background colour
+% panel, if we do not deactivate the \rowcolors action during definition of
+% the headers and footers; this requires extra mark-up. Besides if we
+% deactivate using \hiderowcolors during header and footer formation, the
+% parity of the body rows is shifted, \rownum is even, not odd, at first body
+% row. And setting \rownum at start of first body row is too late for
+% influencing the colour.
+%
+% * it has a global impact and must be reset at each table. We can not
+% issue it only once and it provides no public interface (without @) to
+% cancel its effect conveniently (\hiderowcolors can only be used from
+% *inside* a table.)
+%
+% * its core mechanism which increments the row count is triggered
+% if a \cline is encountered... so this offsets the alternating colours...
+% ... or not if there are two \cline's in the row...
+% (as we will use same mechanism we have to correct this increment).
+%
+% So we need our own code.

+% 0) colour support is enacted via adding code to three hooks:
+% - \sphinxtabletoprulehook (implicit from \sphinxtoprule expansion)
+% - \sphinxtableatstartofbodyhook (explicit from table templates)
+% - \sphinxtableafterendhook (explicit from table templates)
+% additionally special adjustment must be made in \sphinxcline
+%
+\def\sphinxtoprule{\spx@toprule\sphinxtabletoprulehook}
+% \spx@toprule is what is defined by the standard, booktabs and borderless
+% styles.
+% The colorrows class will prepend \spx@table@toprule@rowcolorON into
+% \sphinxtabletoprulehook which a priori is \@empty but can contain user added
+% extra code, and is executed after \spx@toprule.
+\let\sphinxtabletoprulehook \@empty
+\let\sphinxtableatstartofbodyhook\@empty
+\let\sphinxtableafterendhook \@empty
+%
+% 1) we manage these three hooks in a way allowing a custom user extra wrapper
+% environment from a container class to use them as entry point for some
+% custom code. The container code is done first, prior to table templates.
+% So, the style macros will *prepend* the needed color-code to the existing
+% custom user code, so the custom user code can override them. The custom
+% user code should not redefine any of the 3 \sphinxtable...hook macros via a
+% \global\def, but their contents can use \gdef. In fact they probably need
+% to for the first two hooks which are executed from inside the table and
+% a priori need their code to be in a \noalign which limits scope.
+%
+% 2) the table templates and LaTeX writer code make it so that only
+% one of either
+% \sphinxthistablewithcolorrowsstyle,
+% or \sphinxthistablewithnocolorrowsstyle
+% will be inserted explicitly depending on local :class: for table.
+% The global 'colorrows' style in latex_table_style translates at bottom
+% of this file into code for inserting \sphinxthistablewithcolorrowsstyle
+% at end of \sphinxthistablewithglobalstyle. So it is impossible
+% to have first \sphinxthistablewithnocolorrowsstyle, then

+% (not so easy) implementation of the booktabscolorgaps option. This option
+% defaults to true and is not officially documented, as already colorrows is
+% only opt-in, so it is there only as a "turn-off" switch, but if nobody
+% complains in next few months, it will probably be removed altogether at
+% 6.0.0. The reason it exists is because of longtable aspeces described
+% below.
+%
+% As it is used via \sphinxsetup booktabscolorgaps status is not known here
+% and may change locally. So it must be implemented via delayed or
+% conditional code.
+%
+% We do not know the order of execution of \sphinxthistablewithbooktabsstyle

+% MEMO: with longtable \sphinxtoprule, \sphinxmidrule and \sphinxbottomrule
+% are evaluated at time of constructing the headers and footers as boxes
+% (already typeset material and expanded macros; \sphinxbottomrule is also
+% evaluated at very end of table body, i.e. "normally"). So the used colour
+% to fill the booktabs gaps is decided during the headers and footers
+% construction by longtable. Actually they are expanded twice: in firsthead
+% then in head, respectively in foot and lastfoot. But in current design the
+% header row colours are fixed, not alternating, so there is at least no
+% coherence issue there.
+
+% The \spx@arrayrulewidth is used for some complex matters of merged
+% cells size computations.
+% tabularcolumns argument will override any global or local style and
+% trigger the appropriate adjustment of \spx@arrayrulewidth.
+% Notice that this will be bad if the table uses booktabs style
+% but anyhow table with booktabs should not use any | separator.
