Add completely blank rows (before header of existing table)

Hello! I am struggling to find a way to do the following:

I have an existing table which already has a header. When I export the table in excel, however, I need the header of my table to be positioned on row 7 of the new excel spreadsheet, followed by the data in the table itself. I tried with table creator and concatenate, but I cannot get the result i wanted. How do I insert 6 completely blank rows on top of my table (before the header)? I cannot find out also how to export a table from Knime into excel by stating the exact cell address from which i want the data to be populated.

Thank you very much for your help!
