Sorting by a Single Column
Tables may be sorted by a column by clicking the column heading or by clicking a
Sort button (

) that is displayed in a toolbar that drops down when your mouse hovers over the column heading.
The
Sort double arrow button (

) is available when the table is not being sorted by that column; once a column is included in a sort, the button will display the current sort direction and clicking it will reverse the sort. Sorting a column will also update the column heading cell to show the sort direction; the sort direction icon is enabled as a button when you hover over it.
Note: Once you sort on a different column, the previous sort column heading updates to remove the sort direction icon.
