ThinkPHP6如何使用phpexcel导出excel并设置样式

public function save_import(){
    $excleFile = input('excel');
    //读取execel文件
    $path = public_path().$excleFile;
    //实例化PHPExcel类
    $objPHPExcel = new \PHPExcel();
    $objPHPExcel->createSheet(); //创建新的内置表
    $objPHPExcel->setActiveSheetIndex(); //吧新创建的sheet设定为当前活动sheet

    $objPHPExcel->getActiveSheet()->freezePane('A2');//锁定这个单元格，则该单元格所有的左边区域和上方区域都会被锁定，也就是不受滚动条的影响，像浮在那一样，这就是锁定单元格的原理。所以锁定A2就是冻结第一行了
    //设置背景颜色
 		$objPHPExcel->getActiveSheet()->getStyle('A1:M1')->getFill()->setFillType(\PHPExcel_Style_Fill::FILL_SOLID)->getStartColor()->setARGB('D9FFC125');
 		$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(10);
 		$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(20);
 		$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(20);
 		$objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(20);
 		$objPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(20);


    $objSheet=$objPHPExcel->getActiveSheet(); //获取当前活动sheet
    $data=Integrals::order('id', 'asc')->select()->toArray();
   	$objSheet->setTitle("积分兑换");//给当前活动sheet设置名称
   	$objSheet->setCellValue('A1','ID')->setCellValue('B1','卡号')->setCellValue('C1','姓名')->setCellValue('D1','累计积分')->setCellValue('E1','已用积分');
    $j=2;
    foreach($data as $key=>$val){
      $objSheet->setCellValue('A'.$j,$val['id'])->setCellValue('B'.$j,$val['card'])->setCellValue('C'.$j,$val['name'])->setCellValue('D'.$j,$val['integral'])->setCellValue('E'.$j,$val['used_integral']);
      $j++;
    }
    //设置保存的Excel表格名称
	  $filename ="积分兑换 - ".date("Y-m-d").'.xls';
	  //设置浏览器窗口下载表格
	  header("Content-Type: application/force-download");
	  header("Content-Type: application/octet-stream");
	  header("Content-Type: application/download");
	  header('Content-Disposition:inline;filename="' . $filename . '"');
	  //生成excel文件
	  $objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
	  //下载文件在浏览器窗口
	  $objWriter->save('php://output');
	  exit;
