Hello Heath Hensley,
In short, no, the splitter control does not have such a property. Even though you are correct that RadSplitter renders a TABLE and each RadPane control renders a TABLE cell, the splitter does not render just a TABLE and the panes do not render only TABLE cells. This, together with the fact that a couple of features of RadSplitter, that a TABLE element does not have, require width in pixels prevent us from implementing the width of the splitter control as you suggest. The feature that most obviously requires width in pixels is scrolling.
