前言：
在软件实际制作中，为节省开发成本和开发周期，一些软件人员通常会吧DBGrid中的数据直接导出到Excel表中，而先前能看到的函数仅仅只能在WorkBook的一个Sheet中导入数据，不支持多Sheet！。
单元应用：
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, DB, DBTables, Grids, DBGrids, ActiveX, ComObj,
Excel2000, OleServer;
测试环境：
OS：Win2k Pro；Excel2k；Delphi6.0
源程序：
{
功能描述：把DBGrid输出到Excel表格（支持多Sheet）

调用格式：CopyDbDataToExcel([DBGrid1, DBGrid2]);
}
procedure CopyDbDataToExcel(Args: array of const);
var
iCount, jCount: Integer;
XLApp: Variant;
Sheet: Variant;
I: Integer;
begin
Screen.Cursor := crHourGlass;
if not VarIsEmpty(XLApp) then
begin
XLApp.DisplayAlerts := False;
XLApp.Quit;
VarClear(XLApp);
end;
try
XLApp := CreateOleObject('Excel.Application');
except
Screen.Cursor := crDefault;
Exit;
end;
XLApp.WorkBooks.Add;
XLApp.SheetsInNewWorkbook := High(Args) + 1;
for I := Low(Args) to High(Args) do
begin
XLApp.WorkBooks[1].WorkSheets[I+1].Name := TDBGrid(Args[I].VObject).Name;
Sheet := XLApp.Workbooks[1].WorkSheets[TDBGrid(Args[I].VObject).Name];
if not TDBGrid(Args[I].VObject).DataSource.DataSet.Active then
begin
Screen.Cursor := crDefault;
Exit;
end;
TDBGrid(Args[I].VObject).DataSource.DataSet.first;
for iCount := 0 to TDBGrid(Args[I].VObject).Columns.Count - 1 do
Sheet.Cells[1, iCount + 1] :=
TDBGrid(Args[I].VObject).Columns.Items[iCount].Title.Caption;
jCount := 1;
while not TDBGrid(Args[I].VObject).DataSource.DataSet.Eof do
begin
for iCount := 0 to TDBGrid(Args[I].VObject).Columns.Count - 1 do
Sheet.Cells[jCount + 1, iCount + 1] :=
TDBGrid(Args[I].VObject).Columns.Items[iCount].Field.AsString;
Inc(jCount);
TDBGrid(Args[I].VObject).DataSource.DataSet.Next;
end;
end;
XlApp.Visible := True;
Screen.Cursor := crDefault;
