The best way would be to use a stylesheet. Embed something like this at the
top of the page:

<style type="text/css">
.bogus0 {
  background-color: #00ff00;
  border: none;
}

.bogus1 {
  background-color: #ff0000;
  border: none;
}
</style>

And use '<tr tal:attributes="class string:bogus${repeat/item/odd}" ...'

You'd be wanting to use "module_code=options/modcode" in the TAL.
