So by "there is no sorting taking place" you mean you just do
$("#myTable").tablesorter();
And after a click on a link you want the table to look like just after this call with no sorting done?
I don t think there is an easy way to do this. But I provide a hack how this could be done, but beware depending on the size of your table this might use up a good amount of browser memory.
The idea is to copy the table before you apply the tablesorter plugin. Later when clicking the link just restore the table as it was and reapply tablesorter. e.g.
var tablebackup;
$(document).ready(function() {
tablebackup = $("#myTable").clone();
$("#myTable").tablesorter();
});
function resetTable() {
tablebackup.clone().insertAfter("#myTable");
$("#myTable").remove();
$("#myTable").tablesorter();
}
