代码如下：

<script src="//unpkg.com/vue/dist/vue.js">script>
<script src="//unpkg.com/[email protected]/lib/index.js">script>
<div id="app">
<template>
    <el-table
      ref="table1"
      border="10"
      height="150"
      :data="tableData"
      style="width: 800px">
      <el-table-column
        prop="date"
        label="日期"
        width="300">
      el-table-column>
      <el-table-column
        prop="name"
        label="姓名"
        width="300">
      el-table-column>
      <el-table-column
        width="300px"
