npoi垂直对齐中心

Question

我已经尝试了十几种方法来做到这一点，没有什么作品。我尝试将垂直对齐应用到中心。

似乎没有任何工作。

我真的很感谢一些帮助。

这里是我的代码：

 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); 

干杯！
