Export to Excel: XML transformation

Question

Hi,
I have to export the result set on the Grid in an Excel file( fancy report..:) ). The result set has to be modified based on the other tables before downloading. The resulting file has to have the various formatting like color, bold, font size, etc..
As OLE is slow so I am thinking to go for the XML transformation.
Issue:
1. The table had around 100 columns, so is there any way to dynamically read the number of columns being displayed? (The user can change the layout).
Kindly suggest.
Regards
s@k
