Node.js 如何快速导出嵌套列（多表头）的excel文件。效果图如下：
1：使用 @zurmokeeper/exceljs， V4.4.1以上 安装：
npm i @zurmokeeper/exceljs
2: 有一个 worksheet.makeColumns 方法，API文档： 代码示例：
const ExcelJS = require('@zurmokeeper/exceljs');
(async ()=>{
const test = 'test.xlsx';
const workbook = new ExcelJS.Workbook();
const worksheet = workbook.addWorksheet('Sheet1', {
views: [{state: 'frozen', xSplit: 0, ySplit: 2}], // 冻结第1行和第二行
});
// 设置多级表头
worksheet.makeColumns([
{
id: 1,
title: '姓名',
},
{id: 2, title: 'Qwe'},
{id: 3, title: 'Foo'},
{
id: 4,
title: '基础信息',
children: [
{id: 41, title: 'Zoo 1'},
{id: 42, title: 'Zoo 2'},
{id: 44, title: 'Zoo 3'},
],
},
{
id: 5,
title: 'Zoo1',
children: [
{id: 51, title: 'Zoo 51'},
{id: 52, title: 'Zoo 52'},
{id: 54, title: 'Zoo 53'},
],
},
{id: 6, title: 'Foo123213'},
]);
const data = [
[1, 2, 3, null, null, 'DOB'],
[1, 'electron', 'DOB'],
[1, 'electron', 'DOB'],
[1, 'electron', 'DOB'],
[1, 'electron', 'DOB'],
[1, 'electron', 'DOB'],
[1, 'electron', 'DOB'],
[1, 'electron', 'DOB'],
];
worksheet.addRows(data);
worksheet.columns.forEach(function(column) {
column.alignment = {horizontal: 'center', vertical: 'middle'};
});
await workbook.xlsx.writeFile(test);
})()
