Exclude a column from being sorted using jQuery tablesorter

Question

I am looking for a way to exclude a single column from being sorted using jQuery\'s tablesorter plugin. Specifically, I have a fairly large table and would like to keep a \"row

Answer 1

The answer of Brian Fisher is correct, but it is too slow in large tables (+1600 rows in my example). I improved the way of iterating through every rows. Everything else is the same.

$(function() {
    // add new widget called indexFirstColumn
    $.tablesorter.addWidget({
        // give the widget a id
        id: "indexFirstColumn",
        // format is called when the on init and when a sorting has finished
        format: function(table) {               
            // loop all tr elements and set the value for the first column  
            $(table).find("tr td:first-child").each(function(index){
                $(this).text(index+1);
            })                                  
        }
    });

    $("table").tablesorter({
        widgets: ['zebra','indexFirstColumn']
    });
});
