How to get waterstains out of coffee table?

It's a pretty cheap coffee table its maple finish with crappy wood inside, and as soon as I put a cup on it, horrible dark stains appeared on it, so is there any way to get rid of them?

And I don't need any sarcastic remarks about buying cheap things or 'prevention is better than cure', I realise that but that is not helpful now.

Please clean the table top using a glass cleaning liquid, dry it using a dry cloth. In a small piece of cloth, take a little coconut oil and apply it to the whole surface as a very thin film. Now let it stand for an hour or two, You'll see the marks vanish! I use this regularly on my wooden furniture.(Sorry, I have not tried with any other oil!)How to get waterstains out of coffee table?
I don't know and surefire way to get out the water stains but I can tell you a lil trick to make it look as though the water stains have disapeared. I make a paste using a little bit of ground coffee any brand works and water. Use a clean cloth and rub this paste on the areas that have the water stains. Rub till you achieve the desired color Make sure you wipe up all coffee grounds,then let dry. I have been doing this with my coffee table and it still looks good after 6 years of use. Also as I'm sure you have already figured out coasters are a good thing to prevent future water marks, good luck!! :)
lightly sand the top down and varnish it
Take ashes from ashtray and pour on top of stain let it sit a few minutes and then take a cloth to rub it in. Buff with favorite polish. I know it sounds nasty but it works.
