LPS-41306 - Column widths in list of documents and media do not fit text

Hey @aarondelani,

Attached is an update for http://issues.liferay.com/browse/LPS-41306.  Can you test these changes since they are related to SO and changes you have made before.  If everything is good, I can send it to Nate for review.

Please let me know if you have any questions.  Thanks!
