What can't you understand?

The big thing that I was trying to point out in this thread, and which 
Roedy seems to be missing repeatedly, is that sorting a *TREE* is very 
different from sorting a *TABLE*.

Yes, a JTreeTable looks like a JTable (and in fact is implemented using 
an adapter from a JTree to a JTable), but the underlying order is 
determined by the *TREE*. Note that the TreeTableModel extends 
TreeModel, not TableModel!

Once you define how you want to sort your *TREE*, we can help you with 
an implementation. So, give us some information about what is being 
represented in your tree.

Is it a filesystem? If so, sorting the *TREE* could be done by sorting 
the individual files within their directories. e.g. to Sort by file 
size. Of course, it makes no sense to sort the *directories* by size, 
since the intrinsic size of a directory is pretty meaningless unless you 
define it to be the aggregate of the sizes of the files and directories, 
for example. In *that* case, you could sort the tree nodes 
hierarchically so that the directories with the biggest contents show up 
first in the tree.

My ultimate point being: Without defining how you want to sort the tree, 
we can't help you with an implementation.
