前端导出word文件的多种方式以及导出excel文件_Javascript

先看效果：

这是页面中的table

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）

<template>
  <div class="button-box">

前端导出 excel文件，node-xlsx导出文件，行列合并

导出效果：

需要的依赖： node-xlsx

        [22, 2, 3, 4, 5, 6],
      ];

      // 行列合并规则  c：col 列   r:row 行
      const range0 = { s: { c: 0, r: 0 }, e: { c: 0, r: 4 } };
      const range1 = { s: { c: 1, r: 0 }, e: { c: 5, r: 0 } };
      const sheetoptions = {
