I kind of doubt it’s pine; the long little speckles suggest and open-grain hardwood, though the stain makes it hard to determine the species. I’d suspect oak or ash, though the grain doesn’t quite look right for either. If it were pine, I’d expect to see some gouging or dents in a pine table, since pine is so soft. And even with wood conditioner, pine is really difficult to stain, especially dark colors. This would be about the best stain job on pine I’ve ever seen. I’ve done a little experimentation with undercoats/pore sealers for staining blotch-prone woods, and I’ve found wipe-on polyurethane to be the best. Two thin coats of that work reasonably well under gel stain on pine - better than wood conditioner, varnish, and other types of polyurethane. It might work for you here as well, though you’ll still want to at least scuff sand the surface with 320 grit or higher for the poly to bond.
