公司有个需求，是用excel更新数据的，把错误的行列放到一个数组返回出来，正常的数据则插入，且返回数量

1.先需要引入phpspreadsheet，这里使用composer 安装

composer require phpoffice/phpspreadsheet

2.还需要在头部引入，命名空间自己根据vendor目录设置

use Exception;
use PhpOffice\PhpSpreadsheet\Cell\Coordinate;
use PhpOffice\PhpSpreadsheet\Reader\Xlsx;
use PhpOffice\PhpSpreadsheet\Reader\Xls;
use PhpOffice\PhpSpreadsheet\Reader\Csv;

3.下面就是相关代码了，其实逻辑很简单，把excel导入的数据和数据表的字段拼接成二维数组，然后插入就行了

   * @return array
