do_action( 'manage_pages_custom_column', string $column_name, int $post_id )

More Information

Combined with the manage_pages_columns filter, this allows you to add or remove (unset) custom columns to the list page pages. Note that if you are using custom post types and it has ‘hierarchical‘ => true, then you will need to use this action hook and not manage_$post_type_posts_custom_column.
