I have a table of names and ages that I want the user to be able to sort. When the page initally loads, sortList lists the rows in order from oldest to youngest, and then secondarily from A to Z. I want the same thing (a SECONDARY alphabetical sort) when the user actually clicks on the age <th>, but sortForce is making the alphabetical sort primary. Is there an alternative? $('#super_results table').tablesorter({ sortForce: [[0,0]], sortList: [[1,1],[0,0]] }); Or am I misunderstanding sortForce? Documentation here.
