如何從sql導出爲格式化的excel

Question

我有一個與SQL Server數據庫交互的C＃WPF應用程序。在應用程序中，我希望用戶能夠將某些數據從SQL導出到Excel。我試着先填充一個Datatable，然後將其導出到excel文件。一切都很好，直到我遇到了一個任務，充滿了這個SQL查詢的DataTable導出：

到的EXCEL文件是這樣的：出售

所以，我怎麼能進行排序的每selldetails excel文件中的一個區域？ 我已經很長一段時間瞭解這個問題，請幫助我！

萬一如果有人需要以類比的方式解決問題，我用這段代碼實現了目標：

 int currentXLLine = 1; // line in xls file to start 
     int currentId = -1; // current sellID 
     int detailCount = 1; 
     int beginSumLine = currentXLLine+3; 
     for (int i = 0; i < dt.Rows.Count; i++) 
     { 
      if ((currentId != (int)dt.Rows[i][0])) 
      { 

       if (i != 0) 
       { 
        cell = oSheet.Cells[currentXLLine+1, 7]; 
        cell.Font.Bold = true; 
        cell.HorizontalAlignment = ExcelApp.Constants.xlRight; 
        cell.Value = "OVERALL:"; 
        cell = oSheet.Cells[currentXLLine + 1, 8]; 
        cell.Formula = "=SUM(H"+beginSumLine.ToString()+":H" + currentXLLine.ToString() + ")"; 
        cell.Font.Bold = true; 
        cell.HorizontalAlignment = ExcelApp.Constants.xlRight; 

        cell = oSheet.Columns[7]; 
        Past.AutoFitColumn(oSheet, 7); 
        cell.NumberFormat = "# ##0.00"; 
        cell = oSheet.Columns[8]; 
        Past.AutoFitColumn(oSheet, 8); 
        cell.NumberFormat = "# ##0.00"; 
        cell.HorizontalAlignment = ExcelApp.Constants.xlCenter; 

        currentXLLine += 3; 
        detailCount = 1; 

       } 

       oRange = oSheet.get_Range("B" + currentXLLine.ToString(), "C" + currentXLLine.ToString()); 
       oRange.Merge(Type.Missing); 
       oRange.BorderAround(ExcelApp.XlLineStyle.xlContinuous, ExcelApp.XlBorderWeight.xlThin, Microsoft.Office.Interop.Excel.XlColorIndex.xlColorIndexAutomatic, Missing.Value); 
       oRange.HorizontalAlignment = ExcelApp.Constants.xlRight; 
       oRange.VerticalAlignment = ExcelApp.Constants.xlCenter; 
       oRange.EntireRow.Font.Bold = false; 
       oSheet.Cells[currentXLLine, 2] = "SellDate";

       oRange.EntireRow.Font.Bold = false; 
       oSheet.Cells[currentXLLine, 4] = dt.Rows[i][3].ToString(); 
       beginSumLine = currentXLLine + 3; 

       currentXLLine += 2;
