See if the following is what you want

vector1 = {a,b,c}


vector2 = {c,d,e}



{{a*c, a*d, a*e}, {b*c, b*d, b*e}, {c^2, c*d, c*e}}


Note that MatrixForm is such a so-called wrapper that essentially just
changes the way things display on the screen.

It is not necessary to put the 2nd vector in a 1-column format due to
the construction of the Outer[] function.
