# Class TableColumnModelEvent

java.lang.Object
java.util.EventObject
javax.swing.event.TableColumnModelEvent

All Implemented Interfaces:
  `Serializable`

public class TableColumnModelEvent extends EventObject
TableColumnModelEvent is used to notify listeners that a table column model has changed, such as a column was added, removed, or moved.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the `java.beans` package. Please see `XMLEncoder`.
