当行的值与前一行相同时,我需要的是组行,“B3”的值与“B2”相同,如下所示:
我在使用epplus的c#中,我看到我如何使用大纲选项做类似的事情,并且类似于我想要的,但是这个选项有一些缺点,例如那些不自动的基于价值观的群体,不能做各种群体......
是否可以使用EPPLUS执行此操作?如果它不可行,我如何将vba代码添加到c#?,我试试这个:
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();
但无法正常工作,我无法打开Excel文件。
修改
现在使用sugested我尝试使用组函数进行Interop,但是为了一个额外的原因他将列分组而不是行,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;
答案 0 :(得分:5)
我看到这已经得到了回答,但我想我会提供一种EPPlus方式,你当然可以这样做,但你需要手动创建总和单元格:
[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 = "SUM(B2:B10)";
worksheet.Cells["C11"].Formula = "SUM(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:

我不熟悉EPPLUS图书馆。
但您可以使用Microsoft.Office.Interop.Excel
命名空间轻松完成该任务
而且你可以像使用Vba一样(使用Merge()
方法)
请注意,您需要将该命名空间的引用添加到项目中。
这是一个例子:
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Microsoft.Office.Interop.Excel;
namespace WindowsFormsApplication32
{
public partial class Form1 : Form
{
public Microsoft.Office.Interop.Excel.Application ExApp;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
ExApp = new Microsoft.Office.Interop.Excel.Application();
// CREATE A NEW WORKBOOK (you can also open existing workbook using the Open() method)
Microsoft.Office.Interop.Excel.Workbook Wb = ExApp.Workbooks.Add();
// SET WORKSHEET
Microsoft.Office.Interop.Excel.Worksheet Ws = Wb.Worksheets.Add();
// MERGE CELLS (the answer to your question)
Ws.Range["A1:G5"].Merge();
// GROUP ROWS (the final answer to your question)
Ws.Rows["4:7"].Group();
ExApp.Visible = true;
}
}
}
