Hmm, that's the most obvious cause excluded

For a workbook where one sheet is happy and one sheet isn't:
* Take a copy of the file
* Open the copy in Excel, fix the first few rows manually, and save
* Unzip both the original and copy
* In the POI generated file, compare the sheet XML for the "works" sheet
   with the "broken" sheet, especially around style attributes
* Then compare the "broken" sheet XML with the "Excel fixed", for the same
   bits

Hopefully one of those will give a hint about what's going wrong
