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

To the response of James I will only change the sorting function to make it more universal. This way it will sort text alphabetical and numbers like numbers.

if( $.text([a]) == $.text([b]) )
    return 0;
if(isNaN($.text([a])) && isNaN($.text([b]))){
    return $.text([a]) > $.text([b]) ? 
       inverse ? -1 : 1
       : inverse ? 1 : -1;
}
else{
    return parseInt($.text([a])) > parseInt($.text([b])) ? 
      inverse ? -1 : 1
      : inverse ? 1 : -1;
}
