The cell size can be easily accessed with a property node. There is no direct function that returns the cell coordinates. However, they can be calculated with some play with the property nodes. You need to take into account the thickness of the separator lines (1 pixel) and of the table frame, and hide the label and caption.
For the fun, I have added a moving STOP button, that fits the selected cell. Most funny, I found that the button size must be increased by one to fit the cell size successfully. Means that there is a small bug, probably in the cell size property node !
