我需要使用excel-builder.js导出带有样式的excel文件（标题背景颜色蓝色，冻结顶行，列过滤），但是包含所有文档的网站已经无法访问，我什至联系了作者但没有回复。
如果有人可以帮助创建一个包含所有这些格式的小示例，我将非常感激！
我知道以下代码将构建一个 Excel 文件：
var jsonData = [
['sample', 'data', 'for'],
['generating', 'excel', 'in'],
['java', 'script', ' ']
];
require(['excel-builder.js/excel-builder', 'download'], function (EB, downloader) {
var JSworkBook = EB.createWorkbook();
var JSworkSheet = JSworkBook.createWorksheet({name: 'Sheet'});
JSworkSheet.setData(jsonData);
JSworkBook.addWorksheet(JSworkSheet);
var data = EB.createFile(JSworkBook);
downloader('Artist WB.xlsx', data);
});
2024 年 9 月 20 日更新：
项目现在维护在这里：https://github.com/ghiscoding/excel-builder-vanilla
感谢@ghiscoding 的出色工作，也对其进行了升级。
原答案如下：
我添加这个只是因为该项目现已被宣布死亡（https://github.com/stephenliberty/excel-builder.js），并且网站文档已离线（http://excelbuilderjs.com/ ）。因此，我们能做的最好的事情就是找到愿意用分叉来控制它的人，或者分享我们的代码。
服务器端脚本..
<cfscript>
path="/app/uploads/temp/";
full_path=ExpandPath(path) & FORM.filename;
if (!DirectoryExists(ExpandPath(path))) DirectoryCreate(ExpandPath(path));
FileWrite(full_path,(BinaryDecode(FORM.contents,"Base64")));
json=StructNew();
json.file=path & FORM.filename;
WriteJSON(json);
</cfscript>
你可以使用 PHP..
<?php
header("Content-type: ".$_POST['contentType']);
header("Content-disposition: attachment; filename=\"{$_POST['fileName']}\"");
echo base64_decode($_POST['contents']);
?>
或asp..

File.WriteAllBytes(path + request.filename, file_data);

以及页面上的实现..

<i class="fa fa-file-excel-o"></i> Excel
</a>
这是一个表格排序器的完整实现，支持插入 Excel 工作表中的链接，甚至通过简单地将类（.attachTotalsRow）添加到表类 attr 来求和（总计）行。 甚至支持过滤，因此它只抓取由 Excel 表排序器过滤的行，并根据文本宽度自动调整列大小。 您可以看到有几个部分正在开发中，并且有大量稀疏的注释和控制台日志，但它确实有效。 上面是为 ajax 调用设计的，它在 JSON 响应中提供了文件的路径。这样您就可以使用所有设备都支持的浏览器本机点击。通过 javascript 打开新窗口是不安全的，因此这就是采用该方法的原因。因此，顶部的 php 脚本需要更新以模仿 Coldfusion 脚本。
您想要的部分位于 ajax 调用之前的底部。 祝你好运！
您可以通过 网络存档 访问文档的缓存版本。 但请记住，您需要使用缓存 url 语法在文档页面之间导航，而不是仅仅单击链接。
