Column mask when defining grid configuration server side

Hi there

I have a PHP class defining the dHTMLx grid on the server side (using CodeIgniter).
How can I set a mask for a given column server side?

See sample code below

	$config = new GridConfiguration();
	$config->setHeader($this->dhxgrid->getHeader());
	$config->attachHeader($this->dhxgrid->attachHeader());
	$config->setColTypes($this->dhxgrid->getColTypes());
	$config->setColSorting($this->dhxgrid->getColSorting());
	$config->setColAlign($this->dhxgrid->getColAlign());
	$config->setInitWidths($this->dhxgrid->getInitWidths());

	$grid = new GridConnector($this->db, "PHPCI");
	$grid->set_config($config);

Thank you
