JS導出table数据到Excel

首先引入xlsx.full.min.js.

js:

var Main={
    data(){
        return{
            tmpDown:'', //导出的二进制对象
            jsono:[],   // 导出数据样式
        }
    },
    created:function(){
       this.export_style();
    },
    methods:{
        // 導出樣式
        export_style:function(){
            let k=this;
            k.jsono=[];
            for(let i=0;i<k.data1.length;i++){
              k.jsono.push( {
