A couple choices here: If the trunnion hangers will accept 3/8" bolts,
you can drill out the 5/16 holes in the top and tap them for 3/8-16 or
3/8-24 threads, or possibly an appropriate metric size. Another,
perhaps easier way, which will also make it easier to adjust the
trunnions, is to drill right on through the stripped holes, out through
the top of the table. Countersink or counter bore the holes on the top
side so the bolt heads will be flush or slightly below the table top.

You're just going to have to retap the holes for a slightly larger
bolt and perhaps drill out the arbor mounting holes as well to accept
the larger bolt. Outside of replacing the entire top, that's really
your only option. Luckily, it's not that hard to do and I'm sure you
could find someone locally to do it for you if you wanted to go that
Have a competent machine shop look at the problem and suggest the repair.
Probable fixes are to fill the hole with threaded rod and re-tap or to
install helicoil inserts. Have a machine shop do them. Preferably one
where most of the guys look to have showered recently. Neither will be
cheap. Either will be cheaper than buying a new table top.
Thanks to all responders. The holes were repaired with heli-coils for a
cost of $25 which consider a deal. I feel comfortable with the folks at
the shop and am glad to have found a new resource for this kind of work.
