============1、按照官网封装好的样式去写Table组件=======
<template>
 <div>
 <Table></Table>
 </div>
</template>

<script>
 import axios from "axios";
 export default{
 data(){
 return{
 hotFoodData:[],
 selectedFoodData:[],
 columnHotFood:[
  {
  title:"菜名",
  key:"foodName"
  },
  {
  title:"份数(默认为不限份数，文本框输入限制）",
  key:"perlimitFood",
  width:300.
  align:"center",
  ///////////////////////数据双向绑定/////////////////////////////
  render:(h,params)=>{
  return h("Input",{
  props:{
   min:0,
   value:this.hotFoodData[params.index].perlimitFood //设置数字
  },
  on:{
   "on-change":event=>{
   this.hotFoodData[params.index].permitFood=event.target.value;
   }
  }
  });
  }
  },
  {
  type:"selection",
  width:100,
  align:"center"
  },
 ],
 column2: [
   {
    title: "菜名",
    key: "foodName"
   },
   {
    title: "限制份数(默认为不限份数)",
    key: "perlimitFood"
   }
   ]
 }
 methods:{
 }
 };
</script>

============2、向绑定数据中传送数据（后端传送数据、方法中书写）=============
 add() {
  var vm = this;
  //配置热菜菜单
  var urldata =
  "http://192.168.21.210:8016/Food/QueryFoodByShiId";
  axios.get(urldata).then(function(response) {
  vm.hotFoodData = response.data;
  });
 },
 created() {
  this.add();
 }

 
===========3、写勾选传输数据的事件==============
<Table border :columns="columnMainFood" :data="mainFoodData" @on-select="selectRow" @on-select-all="selectAllRow" ></Table>

method中：

//点击左边表格触发事件，向右侧表格添加元素
 selectRow(selection, row) {
  this.selectRowData = row;

  this.selectedFoodData.push(this.selectRowData);
  console.log(this.selectedFoodData);
 },

<Table border :columns="columnMainFood" :data="mainFoodData" @on-select-cancel="selectCancel" ></Table>

method中：

//点击左侧表格，取消勾选，右侧数据也发生改变
 selectCancel(selection, row) {
  console.log("看一下row---------", row);
  this.selectedFoodData.pop(row);
 }
