Maybe there are other possibilities, but whatever they are they are not
obvious and I also have often missed to be able to specify some of the
GridBox Options within TableForm. My guess is that this has historical
reasons. After all there are no gridlines available on text-only-frontends,
and TableForm seems to have existed even before the notebook-frontends were
there...

Anyway, as usual, there are workarounds, e.g.:

DisplayForm[ToBoxes[TableForm[{{a, b}, {c, d}}, 
        TableHeadings -> {{"row1", "row2"}, {"col1", "col2"}}]] /. 
    GridBox[l_, o___] :> GridBox[l,
                                 RowLines -> True,
                                 ColumnLines -> 4,
                                 GridFrame -> 2,
                                 o
                                 ]]

of which you could make a function, probably using the FilterOption-Package
to sort out which options go where. Be aware that the GridBox-Options will
be ignored on a text only frontend...
