当内容较长时，Itextsharp不会创建新页面

我从3天开始尝试制作一个pdf文档，我将感谢任何帮助。

我有几个表单字段访问和填充没有问题。在这个字段的下面，我想放置动态创建的表。这个表格可以很长，可以在不止一页上。这就是我的问题。我不能在同一个页面上添加这个表，表单字段就在它们下面。我找到了合并pdf文件的例子。现在我有了这个场景。

1. 创建一个pdf格式的表格
2. 用pdfTable制作pdf, pdfTable总是只有一个页面，但内容更长
3. 制作pdf，这是从前两个合并。在第一页是填写表单字段，在第二页是我的pdfTable。

我只是想有表单字段和表，从第一页开始，并继续在一些下一页。

我张贴我的代码，这是一个小混乱，但…
