Hi all,
I have started working on this c# library out of necessity. The Export to Excel, Late Binding  code sample from TenTec is nice but I think using the .net library EPPlus for creating the Excel sheet is even better as you don't need to have Excel installed!

Everyone welcome to have a go at it. 

Lots of things could still be implemented. For instance I don't have the grouping part that the TenTec sample has. But I do have multi-row headers.
