Question

我试图在填充我的 excel 文档之前添加一个空行。

using (DataTable dt = new DataTable())
{
    sda.Fill(dt);

    using (XLWorkbook wb = new XLWorkbook())
    {
        var ws = wb.Worksheets.Add(dt, "Report");
        var listOfStrings = new List<String>();
        ws.Cell(1, 6).Value = "Service";
        ws.Cell(1, 15).Value = "Invoice";

        ws.Range("A1:L1").Style.Fill.BackgroundColor = XLColor.DarkBlue;
        ws.Range("M1:Q1").Style.Fill.BackgroundColor = XLColor.DarkCandyAppleRed;
        ws.Range("M2:Q2").Style.Fill.BackgroundColor = XLColor.Red;

        Response.Clear();
        Response.Buffer = true;
        Response.Charset = "";
        Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
        Response.AddHeader("content-disposition", "attachment;filename=Report.xlsx");

        using (MemoryStream MyMemoryStream = new MemoryStream())
        {
            wb.SaveAs(MyMemoryStream);
            MyMemoryStream.WriteTo(Response.OutputStream);
            Response.Flush();
            Response.End();
        }
    }
}

我只需要让第一行为空，然后用我的数据填充文档。但我一直在覆盖文档。

要在工作表第一行上方插入一行，请使用：

ws.Row(1).InsertRowsAbove(1);
                       // ^ number of rows to insert

还有一种方法InsertRowsBelow()可以在某行下方插入新行。有关更多示例，请参阅 documentation。
