使用openXML SAX方法将批量数据写入excel模板

Question

我可以从头开始创建一个excel并将批量数据写入其中，但在使用模板时它无法正常工作。我认为这是由于一些与属性相关的问题而无法纠正的。你能帮忙吗？在模板中前3行是标题和标题，那么我如何跳过这些行并从第4行开始？ 这是我的代码

string newFileName = @"C:\Users\Jeremy\Desktop\OpenXML\Test.xlsm";
using (SpreadsheetDocument spreadSheet = SpreadsheetDocument.Open(newFileName, true))
{
    WorkbookPart workbookPart = spreadSheet.WorkbookPart;
    var openXmlExportHelper = new OpenXmlWriterHelper();
    Sheet sheet = workbookPart.Workbook.Descendants<Sheet>().Where(s => s.Name == "Sheet1").FirstOrDefault();
    WorksheetPart worksheetPart = workbookPart.GetPartById(sheet.Id.Value) as WorksheetPart;
    using (var writer = OpenXmlWriter.Create(worksheetPart))
    {
        writer.WriteStartElement(new Row());
        openXmlExportHelper.WriteCellValueSax(writer, "Cell A4", CellValues.InlineString);
        writer.WriteEndElement(); //end of Row

    }
}
