All Implemented Interfaces:

Serializable, TableModel

public class DefaultTableModel

extends AbstractTableModel

implements Serializable

This is an implementation of TableModel that uses a Vector of Vectors to store the cell value objects.

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^TM has been added to the java.beans package. Please see XMLEncoder.

Constructor Summary
DefaultTableModel()     Constructs a default DefaultTableModel which is a table of zero columns and zero rows.
DefaultTableModel(int rowCount, int columnCount)     Constructs a DefaultTableModel with rowCount and columnCount of null object values.
DefaultTableModel(Object[][] data, Object[] columnNames)     Constructs a DefaultTableModel and initializes the table by passing data and columnNames to the setDataVector method.
DefaultTableModel(Object[] columnNames, int rowCount)     Constructs a DefaultTableModel with as many columns as there are elements in columnNames and rowCount of null object values.
DefaultTableModel(Vector columnNames, int rowCount)     Constructs a DefaultTableModel with as many columns as there are elements in columnNames and rowCount of null object values.
DefaultTableModel(Vector data, Vector columnNames)     Constructs a DefaultTableModel and initializes the table by passing data and columnNames to the setDataVector method.
