Im使用以下代码在posts菜单的后端创建自定义列。

add_filter(\'manage_edit-post_columns\', \'post_edit_columns\');
    function post_edit_columns( $columns )
    {
        $columns = array(
            \'cb\'            => \'<input type="checkbox" />\',
            \'title\'         => \'Module Title\',
            \'categories\'    => \'Section\',
            \'menu_order\'    => \'Order\',
            \'unlock\'        => \'Unlock\',
            \'date\'          => \'Date\'
        );
        return $columns;
    }

Thetitle 列输出ASC/DESC链接。如何将此订购链接添加到其他列？
