Answer 1

S-> ABA is a single production for S row and B->eA is single production for A row. So there is no multiple entries in S and A row.

A -> dA  enters at d column of A row and  A->Bc production enters at e column of A row.
A ->Ɛ enters at Follow(A)= {c, d, e $}

A ->Ɛ and A -> dA are in d column. and A->Ɛ and A->Bc are in e column.

Answer 2
