c# - NPOI 设置单元格样式

Question

C# or VB.NET suggestion are welcome.

我有以下代码用 NPOI 创建 Excel 文件。它工作正常。我需要将单元格样式应用于循环中的那些行。

Dim hssfworkbook As New HSSFWorkbook()

    Dim sheetOne As HSSFSheet = hssfworkbook.CreateSheet("Sheet1")
    hssfworkbook.CreateSheet("Sheet2")
    hssfworkbook.CreateSheet("Sheet3")
    hssfworkbook.CreateSheet("Sheet4")

        Dim cellStyle As HSSFCellStyle = hssfworkbook.CreateCellStyle
    cellStyle.Alignment = HSSFCellStyle.ALIGN_CENTER

      For i = 0 To 9 Step 1
        'I want to add cell style to these cells
        sheetOne.CreateRow(i).CreateCell(1).SetCellValue(i)
        sheetOne.CreateRow(i).CreateCell(2).SetCellValue(i)
  Next

如何将单元格样式应用到上面循环中的那些行？

你需要像这样在循环之外声明 Row 和 Cell:

Dim dataCell As HSSFCell
Dim dataRow As HSSFRow

然后在循环中，您分别为单元格分配值和样式，如下所示:

    dataRow = sheetOne.CreateRow(i)
    dataCell = dataRow.CreateCell(1)
    dataCell.SetCellValue(i)
    dataCell.CellStyle = cellStyle

    dataRow = sheetOne.CreateRow(i)
    dataCell = dataRow.CreateCell(2)
    dataCell.SetCellValue(i)
    dataCell.CellStyle = cellStyle
