Since patron search results are now split into multiple pages, the per-page jquery tablesorter makes for nonsensical sorting. Solution 1: Eliminate the tablesorter (and perhaps expand which columns can be sorted on via the order by option). Solution 2: Eliminate the script-based paging and use the tablesorter paging plugin. I don't think solution 2 is the right one because a poorly refined patron search can result in a very large result set.
