Table Format

Hi, I would like to ask what will the examiner do if he/she sees an answer written in table format rather than paragraph form?

Do I get an instant zero marks for that? Or they do give marks on that?

Thanks in advance.

Note: I’ve already taken the exam and passed but I was wondering why my marks was so near to pass borderline. Want to find out if this is a huge mistake so I don’t carry it on to my P papers.
