element-ui复杂table表格动态新增列、动态调整行以及列顺序详解
更新时间：2023年08月18日 08:35:15 作者：三月的一天
这篇文章主要给大家介绍了关于element-ui复杂table表格动态新增列、动态调整行以及列顺序的相关资料,文中通过代码示例介绍的非常详细,需要的朋友可以参考下
目标：
实现一个复杂table具有以下功能：表格行展开、全部展开、收起、全部收起；可动态配置展示哪些列、调整列展示顺序；动态调整行顺序、行上移、行下移、行移动最顶部、行移动最底部
一、页面效果：
1.全部展开
2.全部收起
3.配置显示列
4.调整字段顺序（拖拽方式）
5.行操作（查看、修改、删除、行上下移动）
二、代码实现（vue+Element-ui）
思路：本质上就是将表格看成一个数组，对表格的操作当成对数组的操作。
