<div> ts.addParser({
  id: "digit",
  is: function(s,table) {
   var c = table.config;
   return $.tablesorter.isDigit(s,c);
  },
  format: function(s) {
   return $.tablesorter.formatFloat(s);
  },
  type: "numeric"
 });</div>
<div> </div>
<div>   $("#my_table").tablesorter({headers: {1: {sorter:'dateYYYY/MM/DD'},   5: {sorter: 'digit'}  },widgets: ['zebra']});</div>
