Problems with pages added by repeating table


#1

Hello,
When I add a table to the last page of an existing pdf document, the rows on the existing page are just fine. However, the new page added by the repeating table has problems.

  1. Added page changes to portrait instead of landscape like the existing page.
  2. Added page no longer has the footer.
  3. Table on the added page is vertically centered, instead of top-aligned.
  4. Scrolling to the last page in Adobe Acrobat shows an error.
    (“An error exists on this page. Acrobat may not display this page correctly. Please contact the person who created the PDF document to correct the problem.”)

Here is the process I use:

  1. I open an existing pdf document.
  2. I create a new table, then add rows and cells to the table.
  3. I add the table to the last existing page of the document.
    LastPage.Paragraphs.Add(table);

Can anyone help with any of the 4 problems? (I am new to pdf programming, so I am probably missing basic concepts.)

Thanks
-Greg

Thank you for contacting support.

Would you please share narrowed down code snippet along with source and generated file so that we may try to reproduce and investigate it in our environment. Before sharing requested data, please ensure using Aspose.PDF for .NET 18.11.

I forgot to mention: I am using 18.11.

I do not see how to upload the 2 pdf files…
