Adding dynamic sorting

It is incredibly easy to add sorting to the table. Open any report which contains the table. Navigate to the Layout tab of the report designer. Click in the cell labeled First Name in the header of the table. Right-click and select Properties. Switch to the Interactive Sort tab. Check the checkbox for 'Add an interactive sort action to this textbox'. Next, set the Sort expression to the value that is displayed in the column – in this case =Fields!FirstName.Value. Now repeat this process for the rest of the report. 

Preview the report, and you should have interactive sorting on each column.
