我的任务是将数据导出到 xls/ xlsx/ xlsm 文件。我成功完成了 xlsx 和 xlsm 文件，但遇到了 xls 问题。

我有带有模板的示例 xls 文件

我正在分享代码。

在这里，GetXLFile 方法使用 SaveFileDialog，它允许用户选择扩展名并选择 xls 文件的位置以导出数据。然后它将给定的文件名和路径保存到“xlFile”字符串。之后，它将模板化的示例 xls 文件复制到 xlFile。你可以在这里找到它的代码。

FillDGVDataToDataTbl 将 datagridview 的数据填充到名为“dataTbl”的数据表中。

在此之后，我将 dataTbl 的数据导出到 xlFile 的选定范围内。“InsertRecords”将数据插入每一行，“InsertColumns”在模板之后的工作表第一行中插入列。

Public Sub ExporttoExcelFile(ByVal dgv As DataGridView)
            Dim dataTbl As New System.Data.DataTable
            Dim xlFile As String = String.Empty
            GetXLFile(xlFile)
           FilDGVDataToDataTbl(dgv, dataTbl)
           Dim ext As String = Path.GetExtension(xlFile)
           If ext.Equals(".xlsx") Or ext.Equals(".xlsm") Then
                 connStr = "Provider = Microsoft.ACE.OLEDB.12.0; Data Source = '" & xlFile & "';" &
                                  " Extended Properties = 'Excel 12.0; HDR = NO; MAXSCANROWS = 0';"
            ElseIf ext.Equals(".xls") Then
                  connStr = "Provider = Microsoft.ACE.OLEDB.12.0; Data Source = '" & xlFile & "';" &
                                   " Extended Properties = 'Excel 8.0; HDR = NO; MAXSCANROWS = 0';"
            End If
            connStr = String.Format(connStr)
            Try
                conn = New OleDb.OleDbConnection(connStr)
                conn.Open()
               cmd = New OleDbCommand()
               cmd.Connection = conn       
               Dim Tbls = conn.GetSchema("Tables", Nothing)
               Dim xlSheet As String
               xlSheet = Tbls.Rows.Item(0)(2).ToString  '("TABLE_NAME").ToString()
        '  If excelSheets(0).EndsWith("$") Then
               Dim lastCol As Char = ChrW(65 + dataTbl.Columns.Count - 1)
               xlSheet = xlSheet.Replace("'", "")
               InsertRecords(dataTbl, xlSheet, lastCol)
          Catch ex As Runtime.Exception
                MsgBox(resManager.GetString("ErrorOccurredWhileExportingPartsListToExcel"), , Me.Text)
          Catch ex As System.Exception
                MsgBox(resManager.GetString("ErrorOccurredWhileExportingPartsListToExcel"), , Me.Text)
          Finally
                conn.Close()
                conn.Dispose()
          End Try

    End Sub

所有这些都运行良好，但视图存在一些问题。

这是所需的视图。

但是，当我打开 xlFile 时，它​​看起来像这样。

（请注意第一行“公司名称”的字体和B、F、H列合并单元格的颜色。这些列的标题字体也发生了变化。）

我没有对 xlFile 进行任何其他更改。谁能告诉我如何获得所需的视图？

提前致谢。
