Dennis,

Here is a slightly neater and clearer version of my earlier posting.

tab1=Flatten[Table[{i,j,k},{i,0,1},{j,0,1},{k,0,1}],2]/.{0->False,1->True};
{P,Q,R}=Transpose[tab1];
och=And[P[[#]],Q[[#]],R[[#]]]&/@Range[Length[tab1]];
eller=Or[P[[#]],Q[[#]],R[[#]]]&/@Range[Length[tab1]];
ellermedfor=Implies[Or[P[[#]],Q[[#]]],R[[#]]]&/@Range[Length[tab1]];
TableForm[Fold[Append,Transpose[tab1],{{},och,eller,ellermedfor}],TableHeadings->{{"P","Q","R"," 
","And[P,Q,R]","Or[P,Q,R]","Implies[Or[A,B],C]"},Range[Length[tab1]]}]
