I'm trying to make a `Grid` that has one cell that spans horizontally and one that spans vertically, like so (generated manually with `Graphics`):

But when I try to do this with Grid, the right-most vertical cell doesn't span both rows:

    Grid[{
    	{ Style["1", FontSize->30], SpanFromLeft, Style["4\n4", FontSize->30] },
    	{ Style["2", FontSize->30], Style["3", FontSize->30], SpanFromAbove }
    }, Frame->All, Spacings->{3,3} ]

Since I have the frame active, I know the right-most cell does in fact span both rows, as we see if we remove `SpanFromAbove`:

    Grid[{
    	{ Style["1", FontSize->30], SpanFromLeft, Style["4\n4", FontSize->30] },
    	{ Style["2", FontSize->30], Style["3", FontSize->30] }
    }, Frame->All, Spacings->{3,3} ]

Is it not possible to combine vertical and horizontal spans in a grid? Is there a better function, like some combination of `Column` and `Row`? Thx
