Vue2.5 结合 Element UI 之 Table 和 Pagination 组件实现分页

1、Element UI 引入(整体引入)

main.js

// Element UI
import Element from 'element-ui'
// 默认样式
import 'element-ui/lib/theme-chalk/index.css'

2、开始封装 iTable.vue 组件 (骨架)

<template>
  <div class="table">
  
     
     <el-table id="iTable">el-table>
     
     
     
     <el-pagination>el-pagination>
     
     
  div>
<template>

3、在页面中引用 iTable 组件，并且给 iTable 组件传值

<template>
  <div class="table-page">
    <!--region table 表格-->
    <i-table
    :list="list"
    :total="total" 
    :otherHeight="otherHeight" 
    :options="options"
    :pagination="pagination"
    :columns="columns" 
    :operates="operates" 
    @handleSizeChange="handleSizeChange"
    @handleIndexChange="handleIndexChange" 
    @handleSelectionChange="handleSelectionChange" 
    @handleFilter="handleFilter" 
    @handelAction="handelAction">
    </i-table>
    <!--endregion-->
  </div>
</template>
<script>
  import iTable from '../../components/Table/Index'

  export default {
    components: {iTable},
    data () {
      return {
        total: 0,
        list: [],
        otherHeight: 208,
        columns: [

          },
          {

            formatter: (row, column, cellValue) => {

            }
          },
