I need to sort a column with a GUID. How to properly set up sorting in jQuery tablesorter?

Question

JavaScript

As I understand it, you need to write and connect your own parser?

$.tablesorter.addParser({
    id: 'countdown',
    is: function () {
      return false;
    },
    format: function ( text, table ) {
     // Тут какой-то код?
    },
    type: 'text'
  });

People, tell me.
