vue2 +elmentui+xlsx10.0.0+xlsx-style
坑有点多。
xlsx10.0.0以后的版本 用require导入或者使用什么导入什么，不要import * xlsx全部导入 ,不然jszip组件报错找不到。
配置文件：
const { defineConfig } = require('@vue/cli-service')
module.exports = defineConfig({
transpileDependencies: true,
configureWebpack: {resolve:{
fallback: {
fs: false,
},
},
externals:{
'./cptable': 'var cptable'
},
}
})
改xlsx-style源码：
