Sorting in List Portlets
Sort the list by a column's value by clicking on the column label. The sort icon (an upward or downward pointing triangle) denotes the column on which the list is sorted. An upward pointing triangle means the list is sorted in ascending (lowest to highest) order. A downward pointing triangle means the list is sorted in descending (highest to lowest) order. To change the sort order of the column, click on the label with the sort icon.
