Hmm, I'm sure you've heard the old homily about having a cake & eating it! :U
The chemicals that produce the odour are volatile, and gradually evaporate so that the smell will fade away over time whatever you do or don't do, and the more exposed & unfinished the wood, the quicker that will happen. How long is a guess, because different trees seem to have different amounts of the volatile chemicals, so it's very variable. I like to use Camphor for drawer-bottoms, & in that situation, the smell persists for many years, but still fades over time. Pieces left on a shelf or in an open wood stack lose most of their smell over a few months, until you plane or cut them again.
Much as you may like your raw table, you are begging for it to become soiled & stained if you don't put something on it to give it a bit of protection. An inescapable fact of life is that tables
will get spills on them, so you either take steps to protect it, or cover it with a plastic sheet & don't use it! What is best to use is a matter of taste as well as technical requirements. Virtually no finish practical for the average DIYer to handle hermetically seals wood, so even 'good' finishes can be penetrated if you are persistent or careless enough.
People who like 'natural' often go for some sort of oil finish. All finishes will yellow a bit over time, but Tung oil is reputed to be the one that does this least. You won't always be able to tell what oil is in it if you buy a proprietary "Danish" oil, but some admit to what's in it on the tin, and it;s usually Linseed, which is one of the more 'yellowing' oils. Danish-type oils give a very pleasing finish on Camphor, but they give
very little 'spill' protection. Condensation rings will certainly leave permanent marks unless wiped off pretty smartly. I like to use a finish like that on something like a bookcase or a blanket chest, but not on a table

You can get a very similar-looking finish that is 'in' rather than 'on' the wood by diluting a satin varnish by 50-60% with turps. Slosh it on, let it soak a bit, then wipe off any excess with a clean rag before it gets sticky (which it will do very quickly, so you need to work reasonably fast). Let that dry, then repeat at least once, better still two or three more times, using even more dilute varnish/turps so it doesn't 'build' too much. This finish is very 'flat', very tactile, & will be a lot more water-resistant than Danish oil. But
all varnishes yellow over time, so you either accept that, or put up with a pretty ragged-looking table top after a year or two.......
