jQuery Table Zebra Striping with hidden rows

I have been using the following with no problems:

$("#tableid tr:even").addClass("evenClass");

But now I have rows in my table that are hidden which messes up the zebra striping styles. I have tried add 'is(":visible")' and things like that to no avail. Any ideas?

Try adding the :visible pseudo-selector:

$("#tableid tr:visible:even").addClass("evenClass");
