Just the layout and behavior of the controls in the form. Do a quick experiment with a customized list form - set it up to manage multiple items, drag the repeating data group onto the form, select Repeating Section (with or without controls) for the control type. Then do it again and select repeating table. Repeating sections give you more layout flexibility - but both control types work on the same data structure (a repeating group with fields in it). If you right click your repeating table and select Change Binding, you'll see how it is bound to the group but the columns displayed are also part of the control binding - not so with a section. Setup a test list, add a few fields and then just add both controls to your form and give it a try.
