Tablesorter Plugin: Sort Alpha is only working in one direction

Tablesorter Plugin: Sort Alpha is only working in one direction

Hi,

I have a sort parser working on a table:

Table - parser for the 'Companies' column

If anyone could tell me why it only works in one direction, that would be great.

code is this:
  1. //table functionality
        var id = -1;
       
        // add parser through the tablesorter addParser method
        $.tablesorter.addParser({
            // set a unique id
            id: 'companies',
            is: function(s) {
                // return false so this parser is not auto detected
                return false;
            },
            format: function(s) {
                var company = $('table.tablesorter tbody td#'+id).text();
                id++;
                return s.replace(company, id);
            },
            // set type, either numeric or text
            type: 'numeric'
        });
        
        $('table.tablesorter > tbody tr').css('background-color', '#fff');
        $('table.tablesorter').tablesorter({sortList: [[0,0]], headers:{1:{sorter:'companies'}}}).children('tbody').children('tr:even').css('background-color', '#dddcc8');






















Thanks!
