The avatars force that whole cell to become taller than it's supposed to be. Thus, short posts will display a lot of blank space because the cell is taller than normal. The only thing you can do is set that cell to valign="top", but then all the blank space will be at the bottom, instead of split between the top and bottom like it is now.
