vue+element-ui+sortable.js实现表格拖拽功能

效果如下:

1.vue使用cli创建项目就不说了,本人使用的是cli3.x版本

2.下载element-ui

npm i element-ui -S

3.引入element-ui,找到main.js,加入如下代码

// 导入element-ui,和全局使用element-ui样式
import ElementUI from "element-ui";
import "element-ui/lib/theme-chalk/index.css";

// 使用 ElementUI 组件库
Vue.use(ElementUI);

4.下载sortablejs,官网为http://www.sortablejs.com/index.html,可在里面看你需要的效果(配置项)

npm install sortablejs --save

5.效果图的全部代码

<template>
  <div style="width:800px">
    <el-table :data="tableData" border row-key="id" align="left">
      <el-table-column
        v-for="(item, index) in col"
        :key="`col_${index}`"
        :prop="dropCol[index].prop"
        :label="item.label"
      >
      </el-table-column>
    </el-table>
    <!-- pre:json数据格式化展示 -->
    <pre style="text-align: left">
      {{ dropCol }}
    </pre>
    <hr />
    <pre style="text-align: left">
      {{ tableData }}
    </pre>
  </div>
</template>
