PHP使用PhpSpreadsheet实现导出Excel时带下拉框列表 (可支持三级联动)

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\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'],['col' => 'D', 'title' => '联系方式', 'field' => 'phone', 'width' => 20, 'id_down_type' => 0, 'is_text' => 1],['col' => 'E', 'title' => '门店', 'field' => 'mendiao', 'width' => 30, 'id_down_type' => 2, 'is_text' => 0],['col' => 'F', 'title' => '公寓', 'field' => 'gongyu', 'width' => 30, 'id_down_type' => 2, 'is_text' => 0],['col' => 'G', 'title' => '门牌号', 'field' => 'menpai', 'width' => 30, 'id_down_type' => 2, 'is_text' => 0],

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
