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:

PHP使用PhpSpreadsheet实现导出Excel时带下拉框列表 (可支持三级联动)_第1张图片

 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:

 '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],
];

// 下拉数据[这里模拟出来数据格式,实际情况从数据库获取数据并整理成下列数据格式]
$oneData = [
    [

    }
    return true;
}

步骤三: 运行php   我这里使用命令行 

php index.php

PHP使用PhpSpreadsheet实现导出Excel时带下拉框列表 (可支持三级联动)_第2张图片

 查看即可

就是如此简单
