我有一个 jsp 文件，它显示一个有 5 列的表格，我想在表格的同一页面上有一个按钮，它可以使用 jquery 以 pdf 格式下载表格的内容。谁能帮助我？我已将 jspdf 的 lib 文件添加到我的项目 js 文件夹中，并在我的 jsp 文件中提供了它们的路径，如下面的代码所示，我不明白出了什么问题，谁能帮忙？

您是否包含了所有 jsPDF lib 文件？

<script type="text/javascript" src="jspdf.js"></script>
<script type="text/javascript" src="./libs/FileSaver.js/FileSaver.js"></script>
<script type="text/javascript" src="./libs/Blob.js/Blob.js"></script>
<script type="text/javascript" src="./libs/Blob.js/BlobBuilder.js"></script>
<script type="text/javascript" src="./libs/Deflate/deflate.js"></script>
<script type="text/javascript" src="./libs/Deflate/adler32cs.js"></script>
