Thank you so much for your quick reply.
I forgot to call the border style so it didn't appear. Thanks for pointing out how brain-dead I can be sometimes!
Here's a follow-up question:
I'm also trying to style for printed output and regardless of what I add to my print-css stylesheet the tables won't respond in a predictable fashion. Is there an easy way to style printed output? Sometimes I call a table directly and can get borders to show up, other times not, background colors, never. Interestingly enough, invoking print media css using the Firefox Web Developer tool does indeed show the styling. An actual print preview does not. I realize this question may be beyond the scope of your plug-in, however, if you have any quick tips I'd appreciate it.
As a test I copied the entire custom css you provided at the end of my print stylesheet... still nothing.
Thanks Tobias for any help you can provide!
