Possible to create table element in report with zero detail cells?

[lisaws]

I am trying to use a table element in my report (iReport Designer Professional 5.2.0) and use zero cells in the Detail section - and instead only use a Group Header.  (In case you're wondering why - it is to make use of Jasper's variables and aggregations rather than relying solely on the SQL query).  Is it possible to use zero Detail cells?  When I try to delete all of the detail cells, I get the following errors:

org.xml.sax.SAXParseException; lineNumber: 213; columnNumber: 18; cvc-complex-type.2.4.b: The content of element 'jr:column' is not complete. One of '{"http://jasperreports.sourceforge.net/jasperreports/components":detailCell}' is expected.<br>Error Trace[/code]

I have tried such workarounds as 1) keeping Detail cells but making their height = 0 px, and 2) having a Detail cell with a blank static text element in it and setting Remove Line When Blank to true on that element.

Nevermind!  I realized that my workaround #1 actually does work (keeping Detail cells but making their height = 0 px).
