Change Row background color based on cell value DataTable

The equivalent syntax since DataTables 1.10+ is rowCallback

"rowCallback": function( row, data, index ) {
    if ( data[2] == "5" )
    {
        $('td', row).css('background-color', 'Red');
    }
    else if ( data[2] == "4" )
    {
        $('td', row).css('background-color', 'Orange');
    }
}

One of the previous answers mentions createdRow. That may give similar results under some conditions, but it is not the same. For example, if you use draw() after updating a row's data, createdRow will not run. It only runs once. rowCallback will run again.

OK I was able to solve this myself:

$(document).ready(function() {
  $('#tid_css').DataTable({
    "iDisplayLength": 100,
    "bFilter": false,
    "aaSorting": [
      [2, "desc"]
    ],
    "fnRowCallback": function(nRow, aData, iDisplayIndex, iDisplayIndexFull) {
      if (aData[2] == "5") {
        $('td', nRow).css('background-color', 'Red');
      } else if (aData[2] == "4") {
        $('td', nRow).css('background-color', 'Orange');
      }
    }
  });
})
