我尝试从3天开始制作一份pdf文件，我将不胜感激。
我有几个表单字段，访问和填充没有问题。在这个字段下面我想放置动态创建的表。此表可以足够长，可以在多个页面上。这是我的问题。我不能将这个表添加到同一页面上，并在其下方使用表单fiels。我找到合并pdf文件的例子。现在我有了这种情况。
我只想拥有从第一页开始的表单字段和表格，并继续下一页。
我发布的代码有点乱，但......

您在代码的第一部分中犯的主要错误是引入Document。没有必要这样做。请阅读我的图书的chapter 6，然后查看C# examples。
您在第二部分中犯的主要错误是使用ColumnText意味着您希望控制布局，但不知道如何处理该控件。如果您使用ColumnText，则需要询问列是否已消耗所有内容。如果没有，您需要自己创建一个新页面。这一点在我的书chapter 3中有所解释。
第三部分看起来不错（据我所知C＃）。
我写了我的书，以便人们可以通过从一开始就编写正确的代码来节省时间。我没有写我的书，所以我必须在StackOverflow上复制/粘贴它们; - ）
