You add a single column to your tree. But you overlay the default cell
component by the checkboxpanel.
So you don't get all the stuff from parent component (Like link and node
icon etc).
Check TreeTable.TreeFragment for details.
You have two opportunities:
1. If you want to add your checkbox directly beside the tree structure
components you have to copy the code from the treetable class
2. If you only want the treestructure in one column (with a link label)
and the combobox in the second column then you have to add
another column on which you don't overwrite newCell (see below)
