element-ui復雜table表格動態(tài)新增列、動態(tài)調(diào)整行以及列順序詳解

 更新時間：2023年08月18日 08:35:15   作者：三月的一天  
這篇文章主要給大家介紹了關(guān)于element-ui復雜table表格動態(tài)新增列、動態(tài)調(diào)整行以及列順序的相關(guān)資料,文中通過代碼示例介紹的非常詳細,需要的朋友可以參考下

目標：

實現(xiàn)一個復雜table具有以下功能：表格行展開、全部展開、收起、全部收起；可動態(tài)配置展示哪些列、調(diào)整列展示順序；動態(tài)調(diào)整行順序、行上移、行下移、行移動最頂部、行移動最底部

一、頁面效果：

1.全部展開

2.全部收起

3.配置顯示列

4.調(diào)整字段順序（拖拽方式）

5.行操作（查看、修改、刪除、行上下移動）

二、代碼實現(xiàn)（vue+Element-ui）

思路：本質(zhì)上就是將表格看成一個數(shù)組，對表格的操作當成對數(shù)組的操作。
