adding columns programatically

[black_lotus]

I have a report with several parameters and static fields. There is also a tabular section with a varying number of columns and rows. I will only know at run-time how many columns there are and so they need to be added to report programatically I guess. They will be added to the detail section. How do I add them programatically though? I've seen samples on how to do it when the whole report has no xml template, but I am using iReport to create a template. Can I get a JasperDesign object from a template or something similar? Or do I need to insert a subreport which will be created programatically and then inserted into the template?

Thanks

take a look on a crosstab side

I'm not sure that will help me. I don't want any row headers, just column headers. It seems to force me to select a row header. The column headers will vary based on user selections (between 3-7).

You can make a row header width = 0

I've read through the iReport manual concerning crosstabs, but I'm still not sure how to achieve what I need. Basically I have an array of javabeans with fields like age, year, amount. There is also a field which is an array of doubles. This field varies in size. It generally has between 1-3 values. So I need to display all of the content in these beans in a table. It would look something like below.

Can you provide a description on how to accomplish this please? Thanks!
