I just started using the current TableSorter ( 2.0.5) ( and JQuery 3.1.1) within my AngularJS app.  I'm getting an error when I click on the table header to sort the table.  The error is on line 614 of tablesorter.js and it says:

caught TypeError: Cannot read property '0' of undefined(…)multisort @ jquery.tablesorter.js:614(anonymous function) @ jquery.tablesorter.js:785

My table consists of strings and numbers.  For example, see attached html

Any idea how to fix this?

Thanks,

Steve
