使用phpoffice/phpspreadsheet导入导出数据

当你在使用phpoffice/phpexcel 类库时候。composer 会给你提示一句话

Package phpoffice/phpexcel is abandoned, you should avoid using it. Use phpoffice/phpspreadsheet instead

phpexcel 已被废弃，建议我们用phpspreadsheet，

包地址：

https://packagist.org/packages/phpoffice/phpspreadsheet

composer：

composer require phpoffice/phpspreadshee

使用:

use PhpOfficePhpSpreadsheetSpreadsheet;
use PhpOfficePhpSpreadsheetIOFactory;
use PhpOfficePhpSpreadsheetStyleNumberFormat;

导出:

//模板下载
    public function template_download()

        //设置第一栏的标题

        $worksheet->setCellValue('C1', '卡号');
        $worksheet->setCellValue('D1', '交易金额');
