Hi Ben,

ECLiPSe does not provide explicit support for tabling. My understanding 
is that tabling is generally supported by extensions to the Prolog 
system at a very low level (the abstract machine), and there are no such 
extensions in ECLiPSe.

I don't know enough about tabling to say how much the features of 
ECLiPSe can help you to program tabling like behaviour in ECLiPSe at the 
ECLiPSe level. You can do a form of memoisation using the store 
non-logical storage feature of ECLiPSe -- this is described in the 
Stores section of the User manual:
