jQuery table sort

Question

I have a very simple HTML table with 4 columns:

Facility Name, Phone #, City, Specialty

I want the user to be able to sort by Faci

Answer 1

This one does not hang up the browser/s, easy configurable further:

var table = $('table');

$('th.sortable').click(function(){
    var table = $(this).parents('table').eq(0);
    var ths = table.find('tr:gt(0)').toArray().sort(compare($(this).index()));
    this.asc = !this.asc;
    if (!this.asc)
       ths = ths.reverse();
    for (var i = 0; i < ths.length; i++)
       table.append(ths[i]);
});

function compare(idx) {
    return function(a, b) {
       var A = tableCell(a, idx), B = tableCell(b, idx)
       return $.isNumeric(A) && $.isNumeric(B) ? 
          A - B : A.toString().localeCompare(B)
    }
}

function tableCell(tr, index){ 
    return $(tr).children('td').eq(index).text() 
}
