Banded column group

If you open a table-style report created by JReport Designer of a version lower than 8, you may find that the table is actually a banded object, and the columns of the table are organized as a banded column group which may contain one or more columns. The banded column group is displayed as BandedColumnInfos in the Report Inspector by default.
