jasper report: custom columns on crosstab - jasper-reports

Question

i would like to know if there is a way to set a custom column after the totals column that give me the crosstab.
I need to print dinamic columns, and the total of them, and add some information at the end but can`t find the way to add custom information after the total column...
did anyone tried to do something similar?

Answer 1

You can do that by adding a top level column group with a constant expression, setting the group header height to 0 and using the group total column to display the additional values. The values could be passed as a measure with calculation="Nothing", or via other means depending on the particular case.
Here's an report that implements my suggestion. It's a modified JasperReports sample report, you can run it with the sample DB in Jaspersoft Studio.
