After canning some tomatoes my wife put the hot jars on a thin towel on ur
kitchen table. It is wood and looks to be finisned in a light oak color.
Where each of the jars were there is a white spot the size of the jars.
Probably due to the heat.
Is there anything that can be done to remove the spots without refinishing
the whole table ?
Gentle prolonged heat might encourage the moisture in the white area
to migrate away. Keep the finish at a very low temperature (maybe 120
F) to avoid damage. Time is your friend, don't rush it. A hair dryer
kept well away from the top might be good source of warrnth.
Hard to believe, but that's actually the best advice in this thread so far.
So far as using abrasives of various types as people have suggested, bad
idea. The last thing you want to do is damage the finish more, or, worse
yet, remove it down to the wood. The idea of using heat is probably a
good one (after waiting for things to settle down).

The classic repair for water spots on wood is mayonnaise. Put a small
dab on a soft cloth and gently rub the white ring. It may or not
work, but worth a try. Buy your wife a cooling rack and a few
none that work. Another I recall seeing is to rub cigarette ashes into
the whitened area, but it did not work for me. The finish has whitened,
not the wood....I would take very fine steel wool and test by rubbing
onto a small part of the whitened area to try to remove that much
finish. You might also remove stain if it is a lacquer finish, so there
are no sure ways to undo the damage. If the white disappears, you can
try patching the finish then with a similar gloss clear finish. If it
is a valuable piece, have an expert look at it. If not valuable,
refinish by sanding the top lightly and put on a clear finish....I've
never seen a spot repair on wood that was satisfactory.
