Tabletop cracking, easy to fix?
I received a dining table for free that seems to be of decent quality, however the tabletop is in rough shape and I would like to repair it. It has small cracks all over the surface that can been seen when light is shined on it, and I can feel them slightly with my fingernail. Hopefully the pictures can show what's going on.
I'm wondering how superficial these cracks are, and what may be required to restore the tabletop. Is this something an absolute beginner woodworker should attempt? I'm handy in other aspects of home maintenance and am willing to research and learn, I just need a nudge in the right direction as to what's going on here and what techniques I should try.
