Found a solution :

string filename = "c:\Test.xls";
Workbook workbook = new Workbook();
Worksheet sheet = new Worksheet("Test")
workbook.Worksheets.Add(sheet)

for(int i = 0;i < 100; i++)
      sheet.Cells[i,0] = new Cell("");

workbook.save(filename);

My work around was to have it fill 100 cells in a for loop with "". That way it gets it's 100 cell count in and then it works just fine.
