------解決方案--------------------
header("Content-type: text/csv");//重要
header('Content-Disposition: attachment;filename="test'.$id.'.xls"');
header('Cache-Control: must-revalidate, post-check=0,pre-check=0');
header("Content-Type:application/vnd.ms-execl");
header('Expires:0');
header('Pragma:public');

這段放到$objWriter->save('my-test'.$id.'.xls');前面去
