VetoableTableColumnModel is an extension to TableColumnModel that can prevent or 'veto' the addition, removal and moving of table columns from happening. Having a VetoableTableColumnModel as the table's and table header's column model can thus prove extremely useful in cases where we do not want specific columns to be removed or moved to a different location. In addition, you can prevent table columns from being added. By default, the TableColumnModels used in Table Library all implement the VetoableTableColumnModel interface.
