To remove the “Container” column in the shipment table is too easy using the remove action hook.
Just copy and paste this code to the theme functions.php file.
remove_action( 'wpcfe_shipment_table_header', 'wpcsc_shipment_container_table_header', 10 ); remove_action( 'wpcfe_shipment_table_data', 'wpcsc_shipment_container_table_data', 10 );
