cd到当前项目，运行

cnpm i element-ui -S

接下来就是在项目里面引用了，打开src目录下的main.js

java 复制代码

//导入vue.js
import Vue from 'vue'
//导入下面2个组件
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
//导入App.vue根组件
import App from './App.vue'
//在导入Vue实例之前，要将element-ui插件加入到Vue中
Vue.use(ElementUI);
Vue.config.productionTip = false

new Vue({
  render: h => h(App),//渲染App根组件
}).$mount('#app')

子组件vue文件中

java 复制代码

<template>
//注意：要在最外层套一个div容器
  <div>
    <el-table
    <！--ref为一个元素或者子组件的应用 -->
    <!-- 组件中所有的ref都会放在$refs属性中>
        ref="multipleTable"
        :data="tableData"
        class="projectnew"
        style="width: 100%"
        @selection-change="handleSelectionChange">
      <el-table-column
          type="selection"
          width="55">
      </el-table-column>

      <el-table-column
          prop="name"
          label="项目名称"

      <el-table-column

        });
