Btw, if you want to play with changing the table alignment, the
enclosed patch changes the alignment to use valign=top for all
tables (and not only for the feature ones).

Don't forget to remove the old theme before testing the
patch with:

	$ rm $(find Documentation/output/ -name theme_overrides.css)

As sphinx (at least version 2.4.4) only writes it if the file
doesn't exist.

Thanks,
Mauro

[PATCH] docs: use top-alignment for table cells

Change the table's default in order to align cells on the top,
overriding the defaults found on Read the Docs Sphinx Theme.
