Text Highlighting or Cell Highlighting

I'm attempting to highlight some text, in my example green for PASS and red for FAIL. I've tried looking through the example templates and have found nothing.

What I want to do in the end is highlight PASS or FAIL when they're added to a table.

do row for var in codevar

|Test____________Result|
|var['test']______var['result']|

should populate

Test___________Result
Test 1__________PASS
Test 2 _________ FAIL

I have this much working but I cannot get any sort of highlighting working. Dynamically as the table is populated or for static text that I test around with.

Any ideas at all? I'm at a complete loss. I've tried bgcolor with xhtml, I've tried out styling but am still confused with how it works.
