The sphinx_rtd_theme does not properly handle wrapping long lines in table cells when rendering to HTML due to a CSS issue (see readthedocs/sphinx_rtd_theme#1505).
Until the issue is fixed upstream in sphinx_rtd_theme, we can simply override the CSS here (in conf.py).
The PRRTE docs don't use the RST ".. list-table::" directive much, so this change won't really have much of an effect here. However, OMPI and PMIx were updated with this conf.py change, so we might as well keep all 3 projects more-or-less in sync.
