前端导出word文件的多种方式以及导出excel文件
作者：夜空孤狼啸
导出功能是项目开发中经常会遇到的需求,在此就前端方面需要做的部分做一个总结,这篇文章主要给大家介绍了关于前端导出word文件的多种方式以及导出excel文件的相关资料,需要的朋友可以参考下
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">
<a-space>
<a-button type="danger" @click="downWord2">模板导出word文件</a-button>

};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
"node-xlsx": "^0.23.0",
代码：
const downXlsx = () => {
let data = [
[1, 222, '', '', '', ''],
['', 2, 3, 4, 5, 6],
['', 2, 3, 4, 5, 6],
['', 2, 3, 4, 5, 6],
['', 2, 3, 4, 5, 6],
[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 = {
'!merges': [range0, range1],
// cols 列宽大小
'!cols': [{ wch: 5 }, { wch: 10 }, { wch: 15 }, { wch: 20 }, { wch: 30 }, { wch: 50 }],
};
//如果不需要格式，这里的sheetOptions可以省略不写
let result = xlsx.build([{ name: 'sheet1', data }], { sheetOptions });
const ab = Buffer.from(result, 'binary');
const blob = new Blob([ab]);
const blobUrl = URL.createObjectURL(blob);
const a = document.createElement('a');
a.href = blobUrl;
a.download = '导出excel.xlsx';
a.click();
window.URL.revokeObjectURL(blobUrl);
