If you want to display as many column footers as there are columns on the page, regardless of the number of strings available, you can use the Column Footer band's PrintIfEmpty property. Setting this property to true will print one footer for each column, regardless of the amount of data available.

 important: It is important to remember that the report generator cannot provide an accurate row count when using the DownThenAcross mode MinRowsInColumn property. Therefore, set the PrintIfEmpty property to true when using the MinRowsInColumn property.
