npoi vertikale Ausrichtung Zentrum

Question

Ich habe ein Dutzend Möglichkeiten versucht, dies zu tun, und nichts funktioniert. Ich versuche, die vertikale Ausrichtung auf die Mitte anzuwenden.

Nichts scheint zu funktionieren.

Ich würde wirklich etwas Hilfe zu schätzen wissen.

Hier ist mein Code:

 var workbook = new HSSFWorkbook(); 

      var sheet = workbook.CreateSheet("Zmiana " + i.ToString()); 

      var headerRow = sheet.CreateRow(0); 

      headerRow.CreateCell(0).SetCellValue("Data"); 
      headerRow.CreateCell(1).SetCellValue("Maszyna"); 
      headerRow.CreateCell(2).SetCellValue("Zmiana"); 
      headerRow.CreateCell(3).SetCellValue("Brygadzista"); 

      int rowNumber = 1; 

      List<MachineStatusReport> listForOneShift = list.Where(c => c.Zmiana == i).ToList(); 

      foreach (MachineStatusReport elements in listForOneShift) 
      { 
       var row = sheet.CreateRow(rowNumber++); 


        row.CreateCell(0).SetCellValue(date.ToShortDateString()); 
        row.CreateCell(1).SetCellValue(elements.Stanowisko); 
        row.CreateCell(2).SetCellValue("Zmiana " + i.ToString()); 
        row.CreateCell(3).SetCellValue(elements.Brygadzista); 
        row.CreateCell(4).SetCellValue(elements.KodProduktu); 
      } 

        NPOI.SS.Util.CellRangeAddress cra = new NPOI.SS.Util.CellRangeAddress(1, counter, 1, 5); 
        sheet.AddMergedRegion(cra); 
      } 

     MemoryStream output = new MemoryStream(); 
     workbook.Write(output); 

Prost!
