2. 使用方式如下:

...

$fileName = '教师信息导入错误记录.xlsx';
    $columns = [
        'name'=>'姓名',
        'idNumber'=>'身份证号',
        'error'=>'错误信息'
    ];
    $excel = new ExcelExportService($fileName);
    $widths = [10, 20, 60];

    $excel->parseColumns($columns);
    $excel->setBody($data);
    $excel->setWidths($widths);

    $excel->save();

    return $excel->getFullFileUrl();

...
