vue 使用 sortable 实现 el-table 拖拽排序功能

npm install sortablejs --save

import Sortable from "sortablejs";

<template>
 <div class="table">
 <el-table ref="dragTable" :data="tableData" border :row-class-name="tableRowClassName">
 <el-table-column prop="date" label="日期"></el-table-column>
 <el-table-column prop="name" label="姓名"></el-table-column>
 <el-table-column prop="address" label="地址"></el-table-column>
 <el-table-column label="操作">
 <template>
 <el-button class="move" type="text" size="small">拖 拽</el-button>
 </template>
 </el-table-column>
 </el-table>
 </div>
