如何加快导出EXCEL的速度？(100分)

我用
//创建Excel工作表
try
ExcelApp:=CreateOleObject('Excel.Application');
MyWorkBook:=CreateOleobject('Excel.Sheet');
except
application.MessageBox(pchar('无法输出数据到Excel，可能是系统中未安装Excel。'),'输出错误',mb_ok+mb_iconstop);
exit;
end;

ExcelApp.Visible:=true;

MyworkBook:=ExcelApp.workBooks.Add;
………………
之类来导出EXCEL，可是导出速度太慢，请问还有什么快的方法快速导出数据表到EXCEL中？

抄来的，还没有试过

试过后要告诉我一下哟

下面的例子是不利用OLE控制Excel把StringGrid导出导XLS文件中。
{2. Without OLE }

procedure XlsWriteCellLabel(XlsStream: TStream; const ACol, ARow: Word;
const AValue: string);
var
L: Word;
const
{$J+}
CXlsLabel: array[0..5] of Word = ($204, 0, 0, 0, 0, 0);
{$J-}
begin
L := Length(AValue);
CXlsLabel[1] := 8 + L;
CXlsLabel[2] := ARow;
CXlsLabel[3] := ACol;
CXlsLabel[5] := L;
XlsStream.WriteBuffer(CXlsLabel, SizeOf(CXlsLabel));
XlsStream.WriteBuffer(Pointer(AValue)^, L);
end;


function SaveAsExcelFile(AGrid: TStringGrid; AFileName: string): Boolean;
const
{$J+} CXlsBof: array[0..5] of Word = ($809, 8, 00, $10, 0, 0); {$J-}
CXlsEof: array[0..1] of Word = ($0A, 00);
var
FStream: TFileStream;
I, J: Integer;
begin
Result := False;
FStream := TFileStream.Create(PChar(AFileName), fmCreate or fmOpenWrite);
try
CXlsBof[4] := 0;
FStream.WriteBuffer(CXlsBof, SizeOf(CXlsBof));
for i := 0 to AGrid.ColCount - 1 do
for j := 0 to AGrid.RowCount - 1 do
XlsWriteCellLabel(FStream, I, J, AGrid.cells[i, j]);
FStream.WriteBuffer(CXlsEof, SizeOf(CXlsEof));
Result := True;
finally
FStream.Free;
end;
end;

// Example:

procedure TForm1.Button2Click(Sender: TObject);
begin
if SaveAsExcelFile(StringGrid1, 'c:/MyExcelFile.xls') then
ShowMessage('StringGrid saved!');
end;

接受答案了.
