我想用一些标题将DataTable导出为excel。我正在使用XLWorkbook导出到excel。我的代码导出DataTable完美excel但我不知道如何添加一些标题。

我想像下面这样的Excel

这是我的c＃代码

   public void ExportDataToExcel(DataTable dt, string fileName)
    {                                          
            using (XLWorkbook wb = new XLWorkbook())
            {
                wb.Worksheets.Add(dt);                    
                wb.Style.Alignment.Horizontal = XLAlignmentHorizontalValues.Center;
                wb.Style.Font.Bold = true;

                Response.Clear();
                Response.Buffer = true;
                Response.Charset = "";
                Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
                Response.AddHeader("content-disposition", "attachment;filename=" + fileName + ".xlsx");

                using (MemoryStream MyMemoryStream = new MemoryStream())
                {
                    wb.SaveAs(MyMemoryStream);
                    MyMemoryStream.WriteTo(Response.OutputStream);
                    Response.Flush();
                    Response.End();
                }
            }                      
    }

这是如何合并excel-worksheet的第一行的单元格：

    //select first row 
    Microsoft.Office.Interop.Excel.Range firstRow = Worksheet.UsedRange.Rows[1];
    //merge the cells of the first row
    firstRow.Merge();
    //set the first rows backcolor to gray
    firstRow.Interior.Color = System.Drawing.Color.Gray;enter code here
    //set the textcolor of the first row to white
    firstRow.Font.Color = System.Drawing.Color.White;
    //set the text to the center of the merged cells
    firstRow.HorizontalAlignment = XlHAlign.xlHAlignCenter;
    firstRow.VerticalAlignment = XlVAlign.xlVAlignCenter;

我希望这有帮助！

根据数据表列大小添加行和合并单元格，然后在此之后添加数据表行。

   if(callrec !=null)
               {
                 DataTable dt = new DataTable();
                  dt.Columns.AddRange(new DataColumn[7] {

                    new DataColumn("RECORDING FILE NAME",typeof(string)),
                    new DataColumn("ACCOUNT NUMBER",typeof(string)),
                    new DataColumn("CALL START TIME",typeof(string)),
                    new DataColumn("AGENT NAME",typeof(string)),
                    new DataColumn("AGENT RESULT",typeof(string)),
                    new DataColumn("DURATION SECONDS",typeof(string)),
                    new DataColumn("PHONE DIALED",typeof(string))

                });
                foreach (var item in callrec)
                {
                    dt.Rows.Add(item.RecFileName,
                        item.AccountNo == "NULL" ? "":item.AccountNo,
                       item.CallStartTime == null ? null : item.CallStartTime,
                       item.agentName=="NULL"? "":item.agentName,
                       item.agentResults=="NULL"?"":item.agentResults,
                       item.DurationSecs,
                       item.phoneDialed=="NULL"?"":item.phoneDialed
                    );
                };
                //Code For Closed XML
                using ( XLWorkbook wb= new XLWorkbook())
                {
                    var ws = wb.Worksheets.Add(dt, "CallRecordingData");
                    ws.Tables.FirstOrDefault().ShowAutoFilter = false;
                    MemoryStream stream = GetStream(wb);
                   // Response.Clear();
                   // Response.Buffer = true;
                   // Response.Charset = "";
                   // Response.ContentType = "application/vnd.openxmlformats- 
    officedocument.spreadsheetml.sheet";
                   // Response.AddHeader("content-disposition", 
       "attachment;filename=" + fileName + ".xlsx");


                }
            }
