在軟件實際制作中，為節(jié)省開發(fā)成本和開發(fā)周期，一些軟件人員通常會吧DBGrid中的數(shù)據(jù)直接導出到Excel表中，而先前能看到的函數(shù)僅僅只能在WorkBook的一個Sheet中導入數(shù)據(jù)，不支持多Sheet！。

單元應用：

  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, DB, DBTables, Grids, DBGrids, ActiveX, ComObj,
  Excel2000, OleServer;

測試環(huán)境：

　　OS：Win2k Pro；Excel2k；Delphi6.0
