Problem

When using the sphinx_rtd_theme, text does not wrap in RST .. list-table:: cells like it does with the default Sphinx HTML theme. For example, the default Sphinx HTML builder theme renders like this:

(FWIW: the LaTeX and text Sphinx builders also render with wrapped text in the cell)

But the sphinx_rtd_theme renders the same RST like this:

The HTML difference between the two appears to be that the sphinx_rtd_theme has this set:

.wy-table-responsive table td, .wy-table-responsive table th {
    white-space: nowrap;
    white-space-collapse: collapse;
    text-wrap: nowrap;
}

Reproducible Project

conf.py:

html_theme = 'sphinx_rtd_theme'

index.rst:

Hello world.

.. list-table::
   :header-rows: 1
   :widths: 10 25

   * - Col 1
     - Col 2

   * - Content
     - This is a long sentence that should wrap nicely in the rendered
       table, but just to make sure, we'll make it super, extra,
       incredibly long.

Expected Results

I expect the words to wrap in the cell, like they do with the default Sphinx HTML builder theme, and with other Sphinx builders.

Environment Info

• Python Version: 3.11.4
• Sphinx Version: 6.2.1
• RTD Theme Version: same results with 1.3.0rc1 and 1.2.2 (didn't manually test back further). This behavior has been around for a long time; I didn't realize that other Sphinx themes / builders wrapped words in a cell until very recently (which is why I didn't file this issue until now).
