Jquery tablesorter plugin and custom parser for streetname + streetnumbers

Jquery tablesorter plugin and custom parser for streetname + streetnumbers

Hello,
 
I'm using the jquery.tablesorter to sort my tables. You can make custom parsers for the plugin, which is also great!
 
Now i'm facing a little problem: I want to sort by streetname and streetnumber.
 
This would be easy if the streetnumber only contained numbers, but they can also contain characters. For example:
 
Lindelaan 8a
Lindelaan 8b
Lindelaan 8c
Lindelaan 18
Lindelaan 32
Lindelaan 86
 
I can create a custom parser like this:
 
  $.tablesorter.addParser({
    id: 'address',
    is: function(s) {
     return false;
    },
    format: function(s) {




   var address = s.split('/');
   var srt = String(address[0]);
      return '' + srt;
    },
    type: 'numeric'
  });




 
 
Can anybody help me with this?
 
Thanks in advance!
