[jQuery] TableSorter 2.0 force update?

[Chris]

I'm playing with adding a filtering widget to table sorting, e.g.
"hide any row where column 7 < 500." Users can keep add or remove
filters dynamically. When they do, I'd like the table to update
immediately, but I don't see how to do that. Calling click() on a
header would change the current sort order. Calling tablesorter()
again seems to break sorting when clicking on columns.
