I have been looking at YUI3 for about a week or two and am very much impressed by it. I came across the this example for making a tree table in YUI 3 (called treeble). I also had a look at YUI 2 and it seems that many of the utilities present in YUI2 have still not propagated to YUI 3, particularly for the DataTable. Is there a way to make the YUI 3 table mutable something like this.
Now I am confused whether to build my app with YUI3 or YUI 2. YUI 3 seems to be more readable and easier to understand but if I use YUI3 I might loose out to some utilities available in YUI 2.
I also came across a method to use YUI 2 objects in YUI 3.
Any suggestions.
