Firefox 3, Chrome issue with table and css(name,value)


I am having problems using something as simple as:
$(".filterable tr:odd").css("background-color", "white");
<table class="filterable">
It works in IE7, but not Firefox 3.0.8 or Chrome (latest stable). I'm
using jQuery 1.3.2.
One thing to note is that "filterable" is not defined in any css
stylesheets. Could the issue be I'm only defining filterable in my
jQuery and not in CSS? Would that be considered an invalid XHTML
issue?
