$upload->rootPath = './Public/uploads/';
$upload->savePath = '';
$info = $upload->upload();

$filename = './Public/uploads/' . $info["updataexcel2007"]["savepath"] . $info["updataexcel2007"]["savename"];
$impFileName = basename($info["updataexcel2007"]['name'],".xlsx");
vendor("PHPExcel.PHPExcel"); //引入phpexcel
$result = $objPhpExcel->getActiveSheet()->toArray(true, true, true, true); //获取表格数据
$pos=ord(max(array_keys($result[1]))); //最大下标ASCII
$objPhpExcel->getActiveSheet()->setCellValue(chr($pos + 1).'1', '姓名'); // 在原有excel上添加列
$objPhpExcel->getActiveSheet()->setCellValue(chr($pos + 2).'1', '年龄');
//循环未添加的列生成数据
for ($i = 2; $i <= count($result); $i++){
$objPhpExcel->getActiveSheet()->setCellValue(chr($pos + 1).$i, '姓名'.$i);
$objPhpExcel->getActiveSheet()->setCellValue(chr($pos + 2).$i,'年龄'.$i);
}
$write = new \PHPExcel_Writer_Excel2007($objPhpExcel);
