PDF format is optimized for viewing, and not for preserving of the semantics of the content. That said, in the general case there is no information in the content indicating that part of the content is a table. The table is, in most cases, just a bunch of paths (borders) and text fragments (words); or even could be an image.
More sophisticated software, like MS Word for example, have the ability to do an OCR analysis of the PDF content elements, and tries to "detect" that a certain content is a table.
That said, the answer to both of your question is no. You can try to detect semantics yourself using RadPdfProcessing
and its document model
, but this would be tricky and will most probably work only for certain classes of PDF documents.
