ss formulated the question :
I may just go for a 3 legged straight legs in the end, This is more than
`less than even` surface as height of some of the slabs differ by as much as
2 inches and it will be next year before I have the time to relay them
properly.

No ordinary table will cope with 2" difference in level without lots of
help.
