Subject: [PATCH] Sugestion

This change will export regular 2D charts as an Excel table without duplicated columns.
Unfortunately I believe this hack can not be applied to more complex chart types (more dimensions), but since I don't use those in my web site I didn't develop a generic fix.
I leave this piece of code here as food for thought. Thanks.
