How to add a DOM element to a Table without moving the other over

[hhicham]

I have something like this:\[code\]<table><tr><td><span style="text-align:center">Some Text</span><img id="myAddButton"></td></tr></table>\[/code\]On the image, I am using jQuery to fade the element in and out (on hover). When this happens, it pushes the other span over and off centers my text. How can I get the button to display while keeping my centered text in the same position?
