el-table进行列的拖拽

1、使用Sortable插件

下载：

npm install sortablejs --save

引入到当前使用的页面

import Sortable from 'sortablejs'

代码重点：可以参考以下代码（不是拿来就可以用的,需要摘取重要代码的内容）

row-key="id" 必须添加且唯一

el-table添加一个id

主要是initSort()方法

<template>
    <div class="diff-container">
        <div>
            <el-table
                v-loading ="loading"
                :data="tableData"
                height="calc(100vh - 180px)"
                style="width: 100%"
                ref="table"
                row-key="branch"
                id="sortExample"
