Remove table.md and ignore it

Seemingly inadvertently added in c7b1629ff5eeae245958d8b7c723ce077075dd40, had some funny consequences in ce98f1eed5c19b986e92b59e367070d86dfeacbf and 0990cde42273122c69f148042ef2b9e2ec1f94ea.
Ignored to ensure this won't happen again by mistake.

Feel free to close this PR if adding the file was voluntary :)
