使用EPPLUS将excel行分组

我需要的是当行的值与上一行相同时对行进行分组，“ B3”的值与“ B2”相同，如下所示：

我在epplus中使用c＃，我看到如何使用outline选项来执行与此类似的操作，并且与我想要的功能相似，但是此选项有一些缺点，例如不能自动基于分组的缺点价值观，不能做各种团体。

EPPLUS是否可以做到这一点？如果不可能，如何将VBA代码添加到C＃中？

  StringBuilder vbaCode = new StringBuilder();

  vbaCode.AppendLine("Sheets('Sheet1').Activate");
  vbaCode.AppendLine("Range('A1: D11').Select");
  vbaCode.AppendLine("Selection.Subtotal GroupBy:= 1, Function:= xlSum, TotalList:= Array(2, 3),Replace:= True, PageBreaks:= False, SummaryBelowData:= True");
pck.Save();

但不起作用，我无法打开Excel文件。

现在有了摘要，我尝试使用group函数进行Interop，但是出于一个额外的原因，他将列而不是行分组，这是代码：

 var ExApp = new Microsoft.Office.Interop.Excel.Application();
 Microsoft.Office.Interop.Excel.Workbooks Wbs = ExApp.Workbooks;
 Microsoft.Office.Interop.Excel.Workbook Wb = Wbs.Open(fi.FullName.ToString());
 Microsoft.Office.Interop.Excel.Sheets wss = Wb.Worksheets;
 Microsoft.Office.Interop.Excel.Worksheet Ws = (Microsoft.Office.Interop.Excel.Worksheet)wss.get_Item("Sheet1");
 Ws.Range["A6:A10"].Group();
 Ws.Outline.SummaryRow =Microsoft.Office.Interop.Excel.XlSummaryRow.xlSummaryAbove;
 ExApp.Visible = true;

我看到已经回答了，但是想出了我会提供一种EPPlus的方法，您当然可以这样做，但是您需要手动创建求和单元格：

[TestMethod]
public void Row_Grouping_Test()
{
    //http://stackoverflow.com/questions/41636336/grouping-excel-rows-with-epplus

    //Throw in some data
    var datatable = new DataTable("tblData");
    datatable.Columns.AddRange(new[]
    {
        new DataColumn("Header", typeof (string)), new DataColumn("Col1", typeof (int)), new DataColumn("Col2", typeof (int)), new DataColumn("Col3", typeof (object))
    });

    for (var i = 0; i < 10; i++)
    {
        var row = datatable.NewRow();
        row[0] = $"Header {i}"; row[1] = i; row[2] = i * 10; row[3] = Path.GetRandomFileName(); datatable.Rows.Add(row);
    }

    //Create a test file
    var fi = new FileInfo(@"c:\temp\Row_Grouping_Test.xlsx");
    if (fi.Exists)
        fi.Delete();

    using (var pck = new ExcelPackage(fi))
    {
        var worksheet = pck.Workbook.Worksheets.Add("Sheet1");
        worksheet.Cells.LoadFromDataTable(datatable, false);

        worksheet.Cells["A11"].Value = "TOTAL";
        worksheet.Cells["B11"].Formula = "SUBTOTAL(9,B2:B10)";
        worksheet.Cells["C11"].Formula = "SUBTOTAL(9,C2:C10)";
        worksheet.Row(11).Style.Font.Bold = true;

        //Row Group 1 (start with 1 since row index is 1-based)
        for (var i = 1; i <= datatable.Rows.Count; i++)
            worksheet.Row(i).OutlineLevel = 1;

        pck.Save();
    }
}

看起来像这样：
