Difference between onMouseOver and onMouseEnter

Question

I\'m trying to have a simple html table, that highlights a row as a user mouses over it. Unfortunately the css hover item doesn\'t work for IE. That leaves me to simulate

Answer 1

Both onmouseenter and onmouseover fire when the mouse enters the boundary of an element. However, onmouseenter doesn't fire again (does not bubble) if the mouse enters a child element within this first element.
