Hi,
In my controller function, I am adding a custom column called 'PC-MB', which doesnot exist in the database. The value is dynamically generated using other values in the row. Which works fine.
My question is - how do I make this column sortable. By default, it is not sortable.
Thanks
$this->load->library('grocery_crud');
$crud = new grocery_CRUD();
$crud->where('is_history',0);
$crud->where('category',"HighwayStats");
$crud->set_table('hwdata');
$crud->order_by('last_update');
$crud->set_subject('Highway Data');
$crud->columns('name', 'last_update', 'PC-MB');
$crud->callback_column('PC-MB',array($this, '_totalpc_callback') );
$gcrud_output = $crud->render();
