public static class SessionStorage.TableProperty
extends Object
implements SessionStorage.Property

A sessionState property for JTable

This class defines how the session state for JTables is saved and and restored in terms of a property called sessionState. We save and restore the width of each resizable TableColumn, if the number of columns haven't changed.

TableProperty is registered for JTable.class by default, so this class applies to JTable and any subclass of JTable. One can override the default with the putProperty method.
