有没有人知道如何通过C#将数据复制到Excel中的表格范围而不会丢失表格格式?

每次我将数据复制到范围时,它都会丢失先前设置的格式。

private object[,] Get2DArrayData()
    {
        var obj = new object[2, 4];
        obj[0, 0] = "Header1";
        obj[0, 1] = "Header2";
        obj[0, 2] = "Header3";
        obj[0, 3] = "Header4";
        obj[1, 0] = 1;
        obj[1, 1] = 2;
        obj[1, 2] = 3;
        obj[1, 3] = 4;
        return obj;
    }

    private void button1_Click(object sender, RibbonControlEventArgs e)
    {
        var worksheet = Globals.ThisAddIn.Application.ActiveSheet;
        Range range = worksheet.Range["A1:D2"];
        Excel.ListObject obj = worksheet.ListObjects.Add(Excel.XlListObjectSourceType.xlSrcRange, range, null, Excel.XlYesNoGuess.xlYes, null);
        obj.TableStyle = "TableStyleMedium3";
        obj.Name = "MyTableNamedRange";
        //table style is lost after setting Value2 on the range
        range.Value2 = Get2DArrayData();
    }

每次我将数组数据粘贴到Value2时,ListObject都会被清除。有没有办法不丢失这种格式?在添加到ListObjects属性之前设置Value2属性是不可能的。

如果要使用数据填充ListObject,则应将ListObject的HeaderRowRange和DataBodyRange设置为内容数组:

obj.HeaderRowRange.Value2 = /* Your array with table headers goes here */
obj.DataBodyRange.Value2 = /* Your array with table data goes here */
