Hold column group together in crosstab

Question

I created a report in iReport with a crosstab containing 2 ColumnGroups. If the crosstab contains more columns than fitting on the page, they are (correctly) continued on the next page. But how can I prevent JR from splitting inside a column group (so if the next column group doesn´t fit on the page, start it on the next page).

Example of colGroups i my crosstab:

Category 1       Category 2      Category 3
C1   C2   C3     C1   C2   C3    C1

Category 3
C2  C3

Answer 1

hope this will useful; inside jasper report on crosstab option there's a checkbox called "keeptogether"; this chekbox keep table on the same page without splitting it
