I'm not sure what you're trying to do, I don't see how that could be laid out correctly like that, say have 5 users and nr 4 has two mobile numbers, won't the second number of nr 4 end up in the place where one would expect the first number of nr 5 even if you could get it to work like that?
Thank you for reply
Actually, I give up dynamics columns in worksheet template, I make the datatable / dynamics columns with richfaces and I want to export with excelExporter.export()
I have an other issue
Follow this thread: http://www.seamframework.org/Community/ExportDatatableExcelWithLotOfData

Sorry for no reply for long time, finally i used the rich:columns and use the seam excel component to export my datatable :)
Thank you :)
