I once implemented something ugly: myarray had a gettable metamethod
that returned a userdata pointing to the begining of a given row. This
temporary userdata had a different gettable method, that returned the
value at a given column.  Back in those days, all userdata were light,
and supported metamethods.  Not sure how bad this would be now that
userdata with metamethods are heavy.
