直接上图：需求：列头和内容都是从返回的数据中获取；现在存在问题：当查询的结果为7条的时候，数据是可以显示（如上图所示）；但是当为一条结果的时候，解析就出问题；代码：<template><p><Table:columns="columnsa"border:data="data1"></Table></p></template><script>exportdefault{data(){return{columnsa:[{title:'班次/日期',key:'name',render:(h,params)=>{returnh('p',[h('strong',params.row.name)]);},},{key:'price1',render:(h,params)=>{returnh('p',[h('Icon',{props:{type:'social-yen'}}),h('strong',params.row.price1)]);},renderHeader:(column,index)=>{letnewIndex=index-1column=this.data1[newIndex].day1;returncolumn}},{key:'price2',render:(h,params)=>{returnh('p',[h('Icon',{props:{type:'social-yen'}}),h('strong',params.row.price2)]);},renderHeader:(column,index)=>{letnewIndex=index-1column=this.data1[newIndex].day2;returncolumn}},{key:'price3',render:(h,params)=>{returnh('p',[h('Icon',{props:{type:'social-yen'}}),h('strong',params.row.price3)]);},renderHeader:(column,index)=>{letnewIndex=index-1column=this.data1[newIndex].day3;returncolumn}},{key:'price4',render:(h,params)=>{returnh('p',[h('Icon',{props:{type:'social-yen'}}),h('strong',params.row.price4)]);},renderHeader:(column,index)=>{letnewIndex=index-1column=this.data1[newIndex].day4;returncolumn}},{key:'price5',render:(h,params)=>{returnh('p',[h('Icon',{props:{type:'social-yen'}}),h('strong',params.row.price5)]);},renderHeader:(column,index)=>{letnewIndex=index-1column=this.data1[newIndex].day5;returncolumn}},{key:'price6',render:(h,params)=>{returnh('p',[h('Icon',{props:{type:'social-yen'}}),h('strong',params.row.price6)]);},renderHeader:(column,index)=>{letnewIndex=index-1column=this.data1[newIndex].day6;returncolumn}},{key:'price7',render:(h,params)=>{returnh('p',[h('Icon',{props:{type:'social-yen'}}),h('strong',params.row.price7)]);},renderHeader:(column,index)=>{letnewIndex=index-1column=this.data1[newIndex].day7;returncolumn}}],//数据data1:[{name:'K1',day1:'06/24',price1:168,day2:'06/25',price2:'',day3:'06/26',price3:158,day4:'06/27',price4:118,day5:'06/28',price5:'',day6:'06/29',price6:198,day7:'06/30',price7:699,}]}},methods:{onRowClick(index){console.log(index);}}}</script>报错如图：各位有什么思路么
