experimenting with modifying css for table

[carns]

Trying to see if a custom css can be used to help with #1044

I'll squash this commit so it doesn't have the history of me trying to figure out which css options to use, but @wkliao can you check the rtd build and see what you think about how this looks? This last iteration simply makes the whole document wider, which I think makes sense for the stuff we have in it. It still uses a scroll bar if the browser is not wide enough to display it entirely.

I think we can use the css approach.
My current implementation adds an empty line to achieve the effect of line break.
It is ugly. See codes below

darshan/darshan-runtime/doc/darshan-runtime.rst

Lines 615 to 617 in 277c6d3

	- Enables Darshan's non-MPI mode, required for applications that do not
	call MPI_Init and MPI_Finalize.

I think using css should do this better. I will make use of this PR to do more testings.

Ok! If you find a better solution we can close this PR and merge something cleaner.

Along the way, I think we can remove the old *.txt and *.css files from the doc directories now that we have switched over?

After a few tries, I think the most critical setting is the full screen width.
Please have a look.
Try adjusting your browser window size to see how the table adopts.

This looks great to me. It avoids wasting all of that whitespace when you are viewing the page on a computer screen, and it still adds horizontal scroll bars to the table if your browser is not wide enough.

Do you want me to squash and merge, or do you want to do it @wkliao ?

[wkliao]

Please squash and merge. Thanks.
