Question

我正在使用iTextSharp库将数据库中的导出详细信息用于PDF。在这里我只想得到如下结果：

Parent Table
Enquiry Details
...........

   IF(Enquiry Have Reply)
   Create First Child Table
   ..............
   ..............
      If(Reply have File)
      Create Second Child Table
       ..........
       ..........

这怎么会返回不正确的表格格式报告。我是否错误地放置了documnt.Add（table）。

这导致了pdf屏幕截图：
