You might try calling the table by ID instead of the generic ‘table’. Also, wrap your JS in a noconflict wrapper like this:
(function($) {
$js162(function(){
$js162("#actArchive").tablesorter({
headers: {
0: { sorter: "text" },
1: { sorter: "digit" },
2: { sorter: false },
3: { sorter: false }
}
});
});
})(jQuery);
