c# - 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，但没有任何效果。我尝试将垂直对齐应用于居中。

似乎没有任何效果。

我非常感谢您的帮助。

这是我的代码:

        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!
