Tables expand to width of display adding lots of white space between columns

[bradbell]

Describe the bug

When I create a table, sphinx-book-theme always expands it to take of the full width of the display, unlike other sphinx themes; e.g., sphinx-rtd-theme and furo. This can result in lots of white space between columns (when the browser window is wide).

In the example below, in the file test_sphinx.git/source/conf.py, if you replace sphinx_book_theme by sphinx_rtd_theme, the table width will contract and not include a huge amount of white space before and after the second column.

Reproduce the bug

git clone https://github.com/bradbell/test_sphinx.git test_sphinx.git
cd test_sphinx.git
mkdir source/_static
git checkout sphinx_book_theme -b temp
make html
firefox build/html/index.html &

Hi, I just came across the same problem, this should be able to be solved by adding the wrapper class that e.g furo uses.
I hope it will be implemented!
https://github.com/pradyunsg/furo/blob/01887051504bbec32e241af9cebcf5cd10f656d1/src/furo/__init__.py#L37
The table-wrapper class then needs atleast the following css overflow-x: auto;

I use furo instead of sphinx-book-theme for my six projects on readthedocs because of this problem; e.g.,
https://xrst.readthedocs.io/latest/

Are there any plans to fix this ?
