Remove columns from WooCommerce admin coupon list
You can use the manage_edit-{post type or taxonomy}_columns filter hook
So you get:
function filter_manage_edit_shop_coupon_columns( $columns ) { // Remove unset( $columns['products'] ); unset( $columns['amount'] ); return $columns;}add_filter( 'manage_edit-shop_coupon_columns', 'filter_manage_edit_shop_coupon_columns', 10, 1 );
