Display a RadioGroup's items in a table like form

I'm trying to place a set of Checkboxes within the same RadioGroup in a tabular fashion.

Something like this:

  [Check1] [Check2]
  [Check3] [Check4]

I tried to have a couple of TableRow objects within the RadioGroup, but that removes the "group behaviour" and allows more than one Checkbox can be selected at the same time.

I am able to put all the items on a single line (by setting the RadioGroup's "orientation" to "horizontal") but not in a grid like style.

Any ideas?
