Looks pretty cool.

It'd be awesome if it were cross-platform (ex: support for  
windows....), you might want to look at FLTK for examples of this sort  
of cross-platformness since they do their own widget management on all  
platforms they use.

Another item that I think is important, especially for being friendly  
w/ memory:
 * On-demand item loading

For example...
	You have a table loaded from a file and have (maybe not necessary,  
but probably important for making scrollbar manageable) read the  
number of rows necessary and have figured column widths to be fixed.
	You have some 1,000,000 elements and obviously don't want them all in  
memory at the same time
	current API doesn't look like it can handle this
Solution:
	Table described in terms of callbacks
		Ex:  function getCell(table, row, column) return textOrWidget......  
end
	Perhaps additional callbacks could be defined such as getRow   to  
reduce the number of calls to the callback in certain
	situations.

This could also work for groups in general .. possibly.. just a matter  
of working out when to load the item...
