Accessibility issue: PDF Tables not correctly formatted

[alexarobu]

Describe the bug
Hi,

It appears that there is an issue with the tables in the PDF version of the metadata records (generated from the records view). It seems that the table is missing formatting and relevant tags.

I couldn't find where the PDF view is configured so I couldn't try to find a solution for this, would you be able to point me in the right direction?

To Reproduce
Steps to reproduce the behavior:

1. View any metadata record (either in default of full view)
2. Download the record as PDF
3. Open the PDF in Acrobat Reader Pro
4. See error in the Tables section of the Accessibility Checker (also in the screenshot below)

Expected behavior
For accessibility, all tables in the PDF must be correctly formatted with headers, rows and regularity.
