如何在EPPlus中对行/列进行分组

有没有一种方法可以在EPPlus中实现这一点？ 只有我能在互联网上find的东西是分组具体的数据，例如：

AAA ---> AAA 5 occurrences AAA BBB 2 occurences BBB BBB AAA AAA AAA 

但在截图中不像视觉效果

看起来你想要做倒塌的行和列轮廓。 这应该演示如何做到这一点：

 [TestMethod] public void Row_Col_Grouping_Test() { //http://stackoverflow.com/questions/32760210/how-to-group-rows-columns-in-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] = String.Format("Header {0}", 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\grouping.xlsx"); if (fi.Exists) fi.Delete(); using (var pck = new ExcelPackage(fi)) { var worksheet = pck.Workbook.Worksheets.Add("Sheet1"); worksheet.Cells.LoadFromDataTable(datatable, true); worksheet.Cells["B12"].Formula = "SUM(B2:B11)"; worksheet.Cells["C12"].Formula = "SUM(C2:C11)"; //Row Group 1 for (var i = 2; i <= 6; i++) { worksheet.Row(i).OutlineLevel = 1; worksheet.Row(i).Collapsed = true; } //Row Group 2 for (var i = 6; i <= 10; i++) { worksheet.Row(i).OutlineLevel = 2; worksheet.Row(i).Collapsed = true; } //Column Group for (var i = 2; i <= 4; i++) { worksheet.Column(i).OutlineLevel = 1; worksheet.Column(i).Collapsed = true; } pck.Save(); } }
