When you want to create more then 255 columns (as supported by excel) you get an error.
The method CreateCell expects an integer as it's first parameter but as soon as you go over 255 it throws an ArgumentException. "Invalid column index (256). Allowable column range for BIFF8 is (0..255) or ('A'..'IV')"
