因项目需要导出Excel表 需要支持下拉 且 还需要支持三级联动功能
目前应为PHPExcel 不在维护，固采用 PhpSpreadsheet
效果如图：
第一步：首先 使用composer 获取PhpSpreadsheet
我这里PHP 版本 7.4 命令如下：
composer require phpoffice/phpspreadsheet第二步：新建php 文件 代码如下 可根据实际情况 自己改动：
<?phprequire './vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\Cell\DataValidation;
use PhpOffice\PhpSpreadsheet\IOFactory;
use PhpOffice\PhpSpreadsheet\NamedRange;
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Style\Alignment;
use PhpOffice\PhpSpreadsheet\Worksheet\Worksheet;
use PhpOffice\PhpSpreadsheet\Cell\Coordinate;
use PhpOffice\PhpSpreadsheet\Style\NumberFormat;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
// 定义表头
$header = [
['col' => 'A', 'title' => '姓名', 'field' => 'name', 'width' => 20, 'id_down_type' => 0, 'is_text' => 1],
['col' => 'B', 'title' => '证件号', 'field' => 'id_card', 'width' => 30, 'id_down_type' => 0, 'is_text' => 1],
['col' => 'C', 'title' => '性别', 'field' => 'gender', 'width' => 20, 'id_down_type' => 1, 'is_text' => 1, 'count' => 2, 'sub_table_name' => 'sex'],

}步骤三： 运行php 我这里使用命令行
php index.php
查看即可
就是如此简单
