出口數據表到Excel中使用EPPlus額外的數據

Question

我有一個要求，在那裏我有生成Excel作爲下面的圖片

我使用EPPlus DLL和我能夠只導出數據表到excel直接使用下面的C＃代碼。

 using (var package = new ExcelPackage(Template)) 
        { 
ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("Product_Reports"); 
      worksheet.Cells["A1"].LoadFromDataTable(dt, true, TableStyles.Medium1);   
      worksheet.Cells[worksheet.Dimension.Address].AutoFitColumns(); 

    ... remainig code 

如何添加標題「Product Statistics」和其他數據，如「Total」，「Sold Out」等，如圖所示？

Answer 1

上eppplus的網站上的例子應該告訴你如何做到這一切，但這裏是一個開始：

[TestMethod] 
public void Table_Export_Test() 
{ 
    //http://stackoverflow.com/questions/31042901/export-datatable-to-excel-using-epplus-with-additional-data 
    //Throw in some data 
    var dtdata = new DataTable("tblData"); 
    dtdata.Columns.Add(new DataColumn("Order no.", typeof (string))); 
    dtdata.Columns.Add(new DataColumn("Product name", typeof (int))); 
    dtdata.Columns.Add(new DataColumn("Name", typeof (int))); 

    for (var i = 0; i < 20; i++) 
    { 
     var row = dtdata.NewRow(); 
     row[0] = i; 
     row[1] = i*10; 
     row[2] = i*100; 
     dtdata.Rows.Add(row); 
    } 


    var existingFile = new FileInfo(@"c:\temp\temp.xlsx"); 
    if (existingFile.Exists) 
     existingFile.Delete(); 

    using (var package = new ExcelPackage(existingFile)) 
    { 
     var ws = package.Workbook.Worksheets.Add("Sheet1"); 
     ws.Cells["A1"].Value = "Product Statistics"; 
     ws.Cells[1, 1, 1, 6].Merge = true; 

     ws.Cells[3, 3].Value = "Total"; 
     ws.Cells[3, 4].Value = "200"; 

     ws.Cells[4, 3].Value = "Sold out"; 
     ws.Cells[4, 4].Value = "50"; 

     ws.Cells[1, 1, 1, 6].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center; 
     ws.Cells[3, 3, 6, 3].Style.HorizontalAlignment = ExcelHorizontalAlignment.Left; 
     ws.Cells[3, 4, 6, 4].Style.HorizontalAlignment = ExcelHorizontalAlignment.Right; 

     ws.Cells[6, 1].LoadFromDataTable(dtdata, true); 

     ws.Column(1).Width = 13; 
     ws.Column(2).Width = 13; 
     ws.Column(3).Width = 13; 
     ws.Column(4).Width = 13; 

     package.Save(); 
    } 

}
