return $sort;
}
// if there is a "fullname" column, sort by first/last name

}示例2: get_sql_sort
/**
* Get the SQL fragment to sort by.
*
* This is overridden to sort by timemodified and ID by default. Many items happen at the same time
* and a second sorting by ID is valuable to distinguish the order in which the history happened.
*
* @return string SQL fragment.
