tp5+phpExcel导出报错 有知道咋回事么

```php
use PHPExcel;
use PHPExcel_IOFactory;


public function export(){
        $objExcel = new PHPExcel();
        $objWriter = PHPExcel_IOFactory::createWriter($objExcel, 'Excel5');

        $objActSheet = $objExcel->getActiveSheet(0);
        $objActSheet->setTitle('领取报表');//设置excel的标题
        $objActSheet->setCellValue('A1', '编号');
        $objActSheet->setCellValue('B1', '姓名');
        $objActSheet->setCellValue('C1', '电话');
        $objActSheet->setCellValue('D1', '区域');
        $objActSheet->setCellValue('E1', '房型');
        $objActSheet->setCellValue('F1', '面积');
        $objActSheet->setCellValue('G1', '总房款');
        $objActSheet->setCellValue('H1', '关注楼盘');
        $objActSheet->setCellValue('I1', '选填楼盘');
        $objActSheet->setCellValue('J1', '添加时间');

        if (!empty($post['pstart_time']) and !empty($post['pend_time']) ) {
            $where['create_time'] = array(
                array('egt', strtotime($post['pstart_time'])),
                array('lt',strtotime($post['pend_time']))
            );
        }
        $data = empty($where) ? Db::name('send')->order('create_time desc')->select() : Db::name('send')->where($where)->order('create_time desc')->select();
        $baseRow = 2; //数据从N-1行开始往下输出 这里是避免头信息被覆盖
        foreach ( $data as $r => $d ) {
            $i = $baseRow + $r;
            $objExcel->getActiveSheet()->setCellValue('A' . $i, $d['id']);
            $objExcel->getActiveSheet()->setCellValue('B' . $i, $d['name']);
            $objExcel->getActiveSheet()->setCellValue('C' . $i, $d['tel']);
            $objExcel->getActiveSheet()->setCellValue('D' . $i, $d['sxregion_id']);
            $objExcel->getActiveSheet()->setCellValue('E' . $i, $d['sxhouse_id'].$d['houseOther']);
            $objExcel->getActiveSheet()->setCellValue('F' . $i, $d['sxarea_id']);
            $objExcel->getActiveSheet()->setCellValue('G' . $i, $d['sxtotal_id']);
            $objExcel->getActiveSheet()->setCellValue('H' . $i, $d['sxbuild_id']);
            $objExcel->getActiveSheet()->setCellValue('I' . $i, $d['house1'].$d['house2'].$d['house3']);
            $objExcel->getActiveSheet()->setCellValue('J' . $i, date("Y-m-d H:i:s",$d['create_time']));
        }
        $objExcel->setActiveSheetIndex(0);
        //4、输出
        $objExcel->setActiveSheetIndex();
        header('Content-Type: applicationnd.ms-excel');
        $time=date('Y-m-d');
        header("Content-Disposition: attachment;filename=导出$time.xls");
        header('Cache-Control: max-age=0');
        header ('Pragma: public');
        $objWriter->save('php://output');
    }

太复杂了，参考下这个标准范例吧，不要直接输出，用文件接受

 $objPHPExcel = new \PHPExcel();
 $sheet = $objPHPExcel->setActiveSheetIndex(0);
