纯前借助word模板端导出word文件（推荐）

先看效果：
这是页面中的table
在这里插入图片描述
这是导出后的效果：

使用模板导出

需要的依赖：
npm 自行安装，需要看官网的具体参数自行去github上面找对应的参数

 	"docxtemplater": "^3.46.0",
    "pizzip": "^3.1.6",
    "jszip-utils": "^0.1.0",
    "file-saver": "^2.0.5",

具体代码：（先看word模板，在看代码，word中的变量和代码中 doc.setData() 是一一对应的）
在这里插入图片描述

前端导出 excel文件，node-xlsx导出文件，行列合并

需要的依赖： node-xlsx
