In many grids, you can sort the displayed data in order to more easily locate a specific record. When a column heading is underlined, the data in the grid can be sorted by that column.
Click the column to sort the data in ascending order.
Click the column again to sort the data in descending order.
On some pages, a white arrow next to the column heading indicates the column by which the grid is currently sorted and whether it is sorted in ascending or descending order.
