title: Fixed Column on a JXTreeTable
body: <p>Im trying to add a fixed column on a JXTreeTable. I've used <a href="https://tips4java.wordpress.com/2008/11/05/fixed-column-table/" rel="nofollow noreferrer">Fixed Column Table</a> and did some adapts to get it working but im having a problem with the collapse event. When i collapse a node on the fixed side it wont collapse on the moving side.</p>
