How to draw a border around both the column header, footer and detail sections?

I have a requirement to have a border that will encapsulate all the details + the column header in a report made in JasperReports + iReport. But if I try to draw a rect or a frame that goes in both the columns header, the details and column footer, I get an error saying that the element position is invalid.

I guess one option would be to use images (just like the good old HTML times without CSS...) but it would be a PITA since if a field overflow or if someone change the height or the width of a section, the image will have to change...

Any other alternatives?

Thanks.
