element ui 的Table封装公共组件！

由于在做项目的时候，很多表格都是一样的格式，我们每次引入这样很浪费空间，将代码量上涨，不如将表格进行封装成一个公共的组件，便于我们随时随刻的调用。

table封装一

在这里去调用组件

对于表格操作的event对象

这是关于表格两项配置colums 和 operation(根据需求，有操作可配置，无操作给operation:[])

下面是封装的公共table组件

<template>
  <div class="table-container">
    <el-table
      :data="data"
      style="width: 100%"

table封装二

采用插槽的方式将操作栏抽离
