Help with tablesorter

I'm trying to use tablesorter as part of a demo I'm preparing.
I have a series of tables built via ajax calls. I had tablesorter
working on one of the tables, but none of the others. Through trial
and error it's not working at all now.
I'd be grateful for any assistance.
Thanks.
