Question

I’m using the jQuery tablesorter plugin and I have a column that contains name of month and year like this

April, 1975
January, 2001

I would like to sort this column as if it were a date column. As I understand it, it is possible to sort the column with some other ‘hidden’ value, but I just can’t seem to find the documentation for that feature. Any help out there?

Update

This fork http://mottie.github.com/tablesorter/docs/index.html of the tablesorter had just what I needed; the ability to store the value to sort by in an attribute, worked really great.

I have a fork of tablesorter that allows you to write a parser that can extract data attributes from the table cell as well as assign specific textExtraction for each column.

$(function(){

  $.tablesorter.addParser({ 
    // set a unique id 
    id: 'myParser', 
    is: function(s) { 
      // return false so this parser is not auto detected 
      return false; 
    }, 
    format: function(s, table, cell, cellIndex) { 
      // get data attributes from $(cell).attr('data-something');
      // check specific column using cellIndex
      return $(cell).attr('data-something');
    }, 
    // set type, either numeric or text 
    type: 'text' 
  }); 

  $('table').tablesorter({ 
    headers : { 
      0 : { sorter: 'myParser' }
    }
  });

});
