When viewing a table, you can sort the table's rows according to any column. By default, table data is sorted by the first column in ascending order. To sort the table rows according to a particular column, click the column's header. Clicking the column header again toggles the sort order between ascending and descending. If you change the sort order in a table, the order is indicated by an arrow in the header of the column by which the table is sorted. The direction of the arrow indicates ascending or descending sort.
