Suggesting the table values to autotag API

Hi,

we are testing the adobe autotagging API with a few specific documents containing tables, images, links and general text elements.

Normally we are getting quite ok results with links, paragraphs and headings, but with tables there is a specific issue where the same document passed through the API is generating different outputs in terms of table tagging. The same document sometimes has correct tagging (Added TH), and when the document is passed again through the tool (the original one, not the alreeady tagged one), the output is different. Bellow the example:

Same table, new document iteration,  without table header

Any idea on how to enusure that the correct version of autottaged document is obtained when passing the document ot the API? Is it possible?

Let me add that the document does not have the tags when adding the document to the API as the tool were we are generating the document (Crystal Reports) does not add any tags to the created PDF.

Would appriciate any suggestion.

Best regards.
