// Interface Option 1:
$this->addRowClass( 'active', function($row) {
  if ($row->status == 'active') {
    return true;
  } else {
    return false;
  }
} );

// Interface Option 2:
$this->addRowAttribute( 'class', function($row) {
  return $row->status;
});

You could also do this for working on a row with javascript:

$this->addRowAttribute( 'data-id', function($row) {
return $row->id;
});
