If it's just seriously scarred from careless use, consider making a new top to fit on top (countersink the screws if metal, or make it a press fit over the existing table if wood, ply, MDF, etc. --very easy to do with strips of wood and a brad nailer). Add rails, t-slots, or add just a sheet to suit.
Don't know what 14" drill press you have -- but most have tables that can actually be improved in terms of functionality.
If there are just some holes in a cast iron table, I've had good luck mixing cast iron chips (I save 'em when band sawing) to JB Weld as a filler. Take a diamond stone or equivalent (fly cut, carefully sand, etc.) to the top after it cures and the bits of cast iron reflect light a bit like the original cast iron. If there are serious holes, you can use fiberglass tape, metal mesh, masking tape etc. to help hold the epoxy/cast iron chips in place before and after it cures.
The problem with trying to find a nice condition drill press table is that if the table is still in mint shape, the rest of the drill press likely is as well. Still, good luck in finding one.
