In[235]:=
mmm=Table[{i,j}, {i,5}]
Table[mmm[[j]],{j,5}]

Out[235]=
{{1,j},{2,j},{3,j},{4,j},{5,j}}

Out[236]=
{{1,1},{2,2},{3,3},{4,4},{5,5}}

Observe, that during table2 pickups, the index j is applied locally to
the elements. I think this may be avoided in the design of biult in
Table function, because this behaviour may have dangerous side effects.
