@blueyeguy Many many thanks:)I have only basic knowledge, sorry. Thats why I did not know where to change the code. But know I understood. If I rename only the label from 'Priority' to 'Department' the sort is still by priority, so I changed it as well.'priority' => array( 'width' => '16%', 'heading' => __('Department'), 'sort_col' => 'dept__name', ),Ones again thank you very much:)
