Introduction
One of the most important tasks in report building is grouping of data. Grouping can be applied either for logic strings with data on a page separation or for making your report look visually better. For rendering reports with grouping use two bands: the GroupHeader and the GroupFooter bands. The GroupHeader bands are put in the beginning of each group. The GroupFooter band is positioned in the end of every group.
