How do I make the jQuery table sorter always initially sort on the last column?

Question

I'm using the JQuery tablesorter v 2.0. I currently have it set up like so

$("#myTable").tablesorter({
    sortList: [[4,0]]
}); 

but how would I set up the default sort order to always be the last column in the table? The reason hard-coding a number may not be ideal is because I'm dynamically generating the table data and sometime the table will have five columns and sometime it will have six.

You could count the number of headers in your table and use that to get the last column index. For example:

// Get the number of "th" within the first "tr":
var columnCount = $('table tr:first').children('th').length;

$("#myTable").tablesorter({
    sortList: [[columnCount - 1, 0]]
});
