如何在EPPlus中分组行/列

本文关键字：EPPlus | 更新日期: 2023-09-27 18:14:16

是否有办法在EPPlus中实现这一点?我在网上唯一能找到的就是对特定数据进行分组例如:

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

但在视觉上不像在截图

如何在EPPlus中分组行/列

看起来您想要折叠行和列轮廓。下面将演示如何执行此操作:

[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();
    }
}
