Each report sorts the table rows by the most-to-least visitors. You can click on any column heading to re-sort the table by that property.
On the first click, your data will be sorted by ascending values. For instance, the Title column will sort alphabetically (A-Z). The second click will sort the data by descending values (Z-A). Subsequent clicks will toggle between ascending and descending sorts.
If you find yourself needing additional flexibility when sorting, this might be a sign that you should try filtering your data.
