Data Regions within table/matrix cells are ignored

Hi,

I have Table and in the Table footer I have another Table.

I get message for inner Table that "Data Regions within table/matrix cells are ignored", when I export the report in Excel, but when I export in PDF, it is fine.

Please tell me is the Table is not a suitable object for this kind of thing.

I have already made around 15 reports using table. Is there any solution, which not require re-writing the whole report.

Thanks,

Sunil
