excel讀寫使用NPOI Library
參考了下列資料後
在 Server 端存取 Excel 檔案的利器：NPOI Library
改寫一下方便自己使用

小弟將其中的函式改寫應用，歡迎自由散布修改，有空將不定期改寫。
請於aspx.cs引用
using NPOI.HSSF.UserModel;
請於aspx.vb引用
Imports NPOI.HSSF.UserModel;
輸出格式主要有兩種：
客戶端（Client）：將資料轉成位元流（Stream）後，在網頁中下載。
MemoryStream ms2 = ExcelUtility.SetFormula(ExcelUtility.RenderDataTableToExcel(table),0,"cos(5)+sin(10)",0,0) as MemoryStream;
// // 設定強制下載標頭。
Response.AddHeader("Content-Disposition", string.Format("attachment; filename=Download.txt"));
// 輸出檔案。
Response.BinaryWrite(ms.ToArray());
主機端（Server）；將資料轉成檔案（File）後，存在主機。
MemoryStream ms2 = ExcelUtility.SetFormula(ExcelUtility.RenderDataTableToExcel(table),0,"cos(5)+sin(10)",0,0) as MemoryStream;
//將資料輸出到主機的檔案aaa.xls
ExcelUtility.SetGridLine(Server.MapPath("./aaa.xls"), ms2, false, new int[] { 0 });
