Hello Per Holmqvist,
The task to make the RadSplitter tableless is pretty complex especially when there are nested splitters - there are problems when the content grows, when the size is in percentages, there are overflow issues, child nodes become bigger than their parents, etc. Also new browsers are introduced, e.g IE8, FF3 and they make the standards more determined. That is why we are considering implementing the splitter only with DIV elements but you should not expect it to be available in the next 6 months.
