先上效果图
使用的插件是xlsx和xlsx-style
npm install xlsx-style --save
npm install xlsx --save
官方文档:xlsx-style
在需要的组件中引入
直接import ‘xlsx-style’ 不起作用，不知道什么原因，
在node-modules中找到xlsx-style中的dist目录中的xlsx.full.min.js粘贴到static里，在index.html引入，具体代码如下
export default {
data() {
return {
invoce_data:{},
wopts:{ bookType: 'xlsx', bookSST: true, type: 'binary', cellStyles: true },

修改行高源码中有，但是官方文档并没有说明，目前没有去研究，应该是可以设置，若有其他问题可以提出讨论。
