我尝试从 3 天开始寻找制作一份 pdf 文档的方法，如果有任何帮助，我将不胜感激。
我有几个表单字段可以毫无问题地访问和填写。我想在此字段下方放置动态创建的表。该表可以足够长，可以包含多个页面。这是我的问题。我无法将此表添加到其下方带有表单字段的同一页面上。我找到了合并 pdf 文件的示例。现在我有这样的场景。
- 制作一份包含填写表单字段的 pdf
- 用pdfTable制作pdf，总是只有一页，但内容较长
- 制作 pdf，将前两个合并。第一页是填写的表单字段，第二页是我的 pdfTable。
我只想拥有从第一页开始并在下一页继续的表单字段和表格。
我发布了我的代码，有点混乱，但是......
