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

More Information

Combined with the manage_{$post_type}_posts_columns filter, this allows you to add or remove (unset) custom columns to the list post/page/custom post type pages (which automatically appear in Screen Options). The action described in here works both for built in post types as well as custom post types. manage_{$post->$post_type}_posts_custom_column can be used in WP 3.1 and later for specific custom post types. Note that if the custom post type has 'hierarchical' => true, then the correct action hook to use is manage_pages_custom_column.
