Using Aspose.PDF, do you have sample codes using accessibility classes to generate a complex layout PDF (WCAG compliant) - just like in the attached file?

Thank you.
We have noticed that there are nested tables in the file which you have shared. We have already logged an investigation ticket as PDFNET-49982 in our issue tracking system to investigate the feasibility of adding tagged nested tables in the PDF. We will surely analyze these requirements and let you know once the ticket is resolved. Please be patient and spare us some time.
We are sorry for the inconvenience.
Thank you… would you know if there is like a timeline on this, if ever? 
We will surely resolve the earlier logged ticket on a first come first serve basis and as soon as we have updates regarding its resolution, we will share with you.
