Sort columnar data
In the 
Sessions and 
People tabs, data is presented in columns.
You can choose which columns to display in the Sessions (left) pane of the Sessions tab. In some cases, you can reorder the columns. Also, in some cases, you can sort data on a particular column.
To sort data on a column, do the following:
-
Click the column header that has the data on which you want to base the sort of the table.
-
To reverse the sort order, click that same column again.
Note
-
You cannot set a secondary or tertiary sort order.
