2.2 RC1 dataTable cell spread out too much, prefer auto fit

[KingdomHeart]

dataTable cell in 2.2 RC1 try to make the width of table equal container width and, cool idea but something making the table look weird. I only have 2 columns table (one hold a profile picture and the other one hold the username), it look very weird because the picture and the name is so far apart from each other. I think I like the 2.1 version better. Is there a way to control this, like make it auto fit if u want to or just leave the default setting.
