FWIW, I think table formatting in Sphinx works via style sheets.
The mechanism is documented in the Python docutils docs that
Sphinx is built upon.
Basically you use the "class" or "role" directive and define
the corresponding CSS or LaTeX (or rst2pdf) style.

Here is one example (using a custom "cssclass" role):
https://pythonhosted.org/sphinxjp.themes.basicstrap/sample.html

Directives (especially role and class):
http://www.sphinx-doc.org/en/stable/rest.html#directives

LaTeX styling:
