Delphi导出Excel的设置操作

procedure CreatRepSheet(SheetName:String;PageSize,PageLay:Integer);
{新建Excel工作簿、进行页面设置}
begin
  {新建Excel工作簿}
  if ExlApp.WorkBooks.Count < 1 then
  begin
    ExlBook := ExlApp.Workbooks.Add; //ExlBook:=ExlApp.WorkBooks[1].WorkSheets[1];
    ExlApp.ActiveSheet.Name:=SheetName;
  end; {if} 

  {进行页面设置} 

  以上是怎么不用空间而调用EXCEL的, 很方便的！
  //设置页面

  if PageLay=1 then
    ExlApp.ActiveSheet.PageSetup.Orientation := xlportrait; //页面放置方向：纵向
  if PageLay=2 then
    ExlApp.ActiveSheet.PageSetup.Orientation := xlLandscape; //页面放置方向：横向 

  //设置页宽自动适应
