目的：使其table中得每个单元格都能做到自定义

新建一个组件 STable.vue

<template>
    <el-table
      :data="list"
      style="width: 100%">
      <el-table-column
        v-for="item in columns"
        :key="item.key"
        :prop="item.key"
        :label="item.title"
        width="180">
        <template slot-scope="scope">
        <ex-slot v-if="item.render" :render="item.render" :row="scope.row" :index="scope.$index" :column="item" />
        <span v-else>{{ scope.row[item.key] || '-' }}</span>
      </template>
      </el-table-column>
    </el-table>
</template>

<script>
// 自定义内容的组件
  var exSlot = {
    functional: true,
    props: {
      row: Object,
      render: Function,
      index: Number,
      column: {
        type: Object,
        default: null
      }
    },
    render: (h, data) => {
      const params = {
        row: data.props.row,
        index: data.props.index
      }
      if (data.props.column) params.column = data.props.column
      return data.props.render(h, params)
    }
  }
export default {
    components: {
        exSlot,
    },
    props:{
            columns:{
                type:Array,
                default:()=>[]
            },
            list:{
                type:Array,
                default:()=>[]
            }
        },
      data() {
        return {
          tableData: [{
            date: '2016-05-02',
            name: '王小虎',
            address: '上海市普陀区金沙江路 1518 弄'
          }, {

            name: '王小虎',
            address: '上海市普陀区金沙江路 1517 弄'
          }, {
