I\'m using this code to create a table from csv for my documentation in readthedocs:
.. csv-table:: Markram et al. Model & Network configuration file
:fi
Immediately before your .. csv-table
directive, put this above with a blank line separating (see https://stackoverflow.com/a/46195021/2214933):
.. rst-class:: table-myclass
.. csv-table:: blah blah blah
The above will apply a class name to the rendered HTML table.
Then in your Sphinx theme, add a custom style. Assuming you want to limit the height of each table row (not the table itself since 100px is pretty short for a lot of data) put the following:
table.myclass tbody tr {height: 100px;}
Adjust the CSS selector and style to taste.
See how to create custom styles in Sphinx.
