Here, you define the header and footer lines for a table group. The overview shows one line for each column available in the table.
In the Group Header field, you can provide a static text as a headline for the table groups.
With the check boxes, you define the summary information shown as a footer for the table group. You can only select the check boxes for table columns containing numbers. It is not possible to generate summary information on columns containing text.
In the Summary Label row, you can define a customized name for each summary function (for example, Min or Max).
The customized names of the functions are automatically written into the column left to the one for which you configured the first summary calculation. If you configured a summary calculation in the leftmost table column, an additional column will automatically be added to the left of this column.
