compare two columns using datatables

Question

My goal is to highlight a row if two columns contain the same string within a row using datatables I am not sure how would I compare two columns. I want to do something like this. This is part of my code

  "columnDefs":[
  {
      "targets":[3,4], 
      "render": function ( data, type, full, meta ) { 
       if value of 3 = 4 {
         //highlight the row
       }
      }
   } ],

Thanks in advance.

SOLUTION

Use rowCallback option to define a callback function that will be called when row would be drawn.

$('#example').dataTable({
  "rowCallback": function(row, data, index){
    if (data[3] === data[4]) {
       $(row).addClass('selected');
    }
  }
});
