There was a problem hiding this comment.
It is possible to do something like
\newcolumntype{X}[2]{p{\dimexpr(\linewidth-\arrayrulewidth)*#1/#2-2\tabcolsep-\arrayrulewidth\relax}}
in sphinx.sty and then generate mark-up by writer like
|X{50}{70}|X{20}{70}|
for smaller files. I must check which letter is best available for this (i.e. not used by packages user may add to default config).
Fortunately \dimexpr handles <dimen>*A/B in double precision for the first multiplication so that even with things like 500/1000 there will be no overflow, despite the maximal dimension in TeX being only about 5.76 m.

I forgot to mention i my review that it would be desirable in future in case columns are narrow not to automatically widen to the full available width, as it seems HTML behaves this way. But this does not look like easy problem in LaTeX without dedicated package. Will check tabulary documentation. |

Merged. Please update macros as you like :-) |
The ``\X`` token is used as column-specifier: this does not define or redefine ``\X`` as a LaTeX macro. Using a letter could have led to conflict with user extra packages or macro definitions. This column specifier takes two arguments which must be positive integers, as produced by LaTeX writer for ``:widths:`` option or for equal widths columns. As it always uses ``\linewidth`` the latter was not abstracted into a third argument.
