How to insert/remove a new row(node) in a jXtreetable?

I'm trying to use JXTreeTable from the SwingLabs library org.jdesktop.swingx.JXTreeTable. I've a problem when I try to insert/remove a node into/from the table.

The fact is that I was expected to have a method that could fire the JXTreeTable when the data in its model change. But I didn't find anything like this. Could anyone tell me how to add or remove a node (parent or child) in a JXTreeTable?

PS: my model class extends AbstractTreeTableModel. I pass in its constructor a LinkedList and populate the JXTreeTable with the data contained in this List

The AbstractTreeTableModel has a protected member variable modelSupport of the type TreeModelSupport, which offers you a variety of such event methods:

• fireNewRoot()
• fireTreeStructureChanged(TreePath)
• firePathChanged(TreePath)
• fireChildChanged(TreePath, int, Object)
• fireChildrenChanged(TreePath, int[], Object[])
• fireChildAdded(TreePath, int, Object)
• fireChildRemoved(TreePath, int, Object)
• fireChildrenAdded(TreePath, int[], Object[])
• fireChildrenRemoved(TreePath, int[], Object[])
• addTreeModelListener(TreeModelListener)
• removeTreeModelListener(TreeModelListener)
