如何经过xlsx-style 修改导出excel的样式

如何经过xlsx-style 修改导出excel的样式

实现导出的excel是带有边框的，知足打印的时候能够尽量的铺满A4纸

安装 xlsx-style

npm install xlsx-style --save复制代码

修改xlsx-style 源码 解决报错

在\node_modules\xlsx-style\dist\cpexcel.js  
var cpt = require('./cpt' + 'able');  改成   var cpt = cptable; 
复制代码

修改vue中的代码

import XLSX from "xlsx";
import XLSXS from "xlsx-style"

        methods:{
            toExcel(){
                let wb = XLSX.utils.table_to_book(this.$refs.table,{sheet:'分组表'})
                this.setExlStyle(wb['Sheets']['分组表'])
                //合并单元格边框补齐
                this.addRangeBorder(wb['Sheets']['分组表']['!merges'],wb['Sheets']['分组表'])
                var ws = XLSXS.write(wb, {
                    type: "buffer"
