14  * An extension to the TableColumnModel that adds logic dealing with the
15  * "visibilty" property of the TableColumnExt. If a column is made invisible,
16  * then the ColumnModel must not return that column in subsequent calls to
17  * <code>getColumnXXX</code>. In other words, it is "silently" removed from
18  * the column model until it is again made visible. However, a change in the
19  * visibility status of a column will trigger an event so that the underlying
20  * JTable can repaint/relayout itself.
21  *
22  * The semantics behind removing a column and making it invisible are two
23  * different things. When a column is removed, it is no longer associated
24  * with the model in any way, whereas an invisible column is simply not
25  * displayed. This is somewhat similar to the idea of column ordering being
26  * different in the model from the view.
