I don't know a thing about tea tables, but some oils and waxes can smell very strongly. That might interfere with your enjoyment of the tea.
With wooden kitchen utensils (e.g. knife handles), I usually use Clapham's Beeswax Salad Bowl Finish. It has a pleasant, light, beeswax scent and there is never any worry about its being toxic. Of course you are not drinking tea
off your tea table, but still...
There are probably better solutions out there, but there's nothing quite like proposing an idea to encourage other people to pipe up with theirs
