[jQuery] Tablesorter plugin problems with zebra stripes

[asle]

Hi
The tablesorter 2.0 plugin is very nice and works great but I don´t
really get how the zebra widget works. I do not get alternate colors
on the table. I have a style for ".odd" and ".even" in CSS. I looked
at the demos and it seems that the TRs are assigned "odd" and "even"
but that does not happen for me. What am I missing? I try this:

$("#tablesorter-demo").tablesorter({10: { sorter: false}, widgets:
['zebra']});
