I want to change the table coror, or make it transparant, is that possible?
Since phpBB is stylesheet-based, you can achieve this in the administration panel in the Styles/Themes category. Delete a color code, e.g. EFEFEF and the background will be transparent so the color "behind" it can "shine" through.
Look into this thread: http://www.phpbb.com/phpBB/viewtopic.ph ... rent+table
P.S. This is a Styles development thing, maybe anyone can move tihs?
