> **element-ui el-table功能很强大，也很好用，但是组件写起来有些麻烦，需要进一步封装，下面是一个封装的例子，可以 formatData，可以利用 slot 动态传递模板，大家觉得有用可以看看**

const columns = [{ key: 'name', minWidth: 150, fixed: true, showOverflowTooltip: true}, { slot: 'actions'}];
    
    <v-table :data="data" :columns="columns">
      <template slot="actions">
        <<el-table-column>
       <el-button @click="buttonClick"></el-button>
    </<el-table-column>
    </template>
    <v-table>

<template>
      <e-table
        :data="data"
        :border="!!border"
        style="width: 100%"
