Table cell text does not wrap in ".. list-table::" #1505

jsquyres · 2023-08-19T18:57:33Z

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).

The text was updated successfully, but these errors were encountered:

Filed PR #1506 which potentially fixes the issue.

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. This commit overrides the CSS in conf.py and also touches up some places where we previously tried to work around the lack of word wrapping. Signed-off-by: Jeff Squyres <jeff@squyres.com>

I noted on PR #1506:

I am not an expert in front-end dev things, but it looks like theme.css might actually be generated, and the source of the wy-table-responsive CSS stanzas comes from https://github.com/snide/wyrm/blob/master/sass/wyrm_core/_table.sass#L144-L151

Unfortunately, it looks like wyrm_core hasn't changed since early 2015. Indeed, snide/wyrm#13 is a PR about sphinx_rtd_theme, but it has sat there unmodified and un-merged since 2018. I'm guessing that filing a PR over there to change the upstream source is unlikely to get merged.

What's the best way to get word wrapping enabled in sphinx_rtd_theme tables?

I think you can remove the "Needed: replication" label since the issue is visible at https://sphinx-rtd-theme.readthedocs.io/en/latest/demo/lists_tables.html#list-tables

The sphinx-rtd-theme currently disables word wrap in table cells due to a bug: readthedocs/sphinx_rtd_theme#1505 This is fixed by overriding the CSS and enabling word wrapping.
