A comprehensive example of jtable in swing, including inserting a row of records in a table and sorting the table columns

By implementing the replicacttablemodel interface, you can add a row of records to the table.

import java.awt.BorderLayout;   import java.awt.Point;   import java.awt.event.ActionEvent;   import java.awt.event.ActionListener;   import java.awt.event.ComponentAdapter;   import java.awt.event.ComponentEvent;   import java.util.Vector;     import javax.swing.JFrame;   import javax.swing.JScrollPane;   import javax.swing.JTable;   import javax.swing.JTextField;   import javax.swing.JViewport;   import javax.swing.SwingUtilities;   import javax.swing.table.AbstractTableModel;     public class RowAdder extends JFrame {       final SimpleModel tableData = new SimpleModel();     JTable table = new JTable(tableData);       public static void main(String[] args) {       RowAdder ra = new RowAdder();       ra.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);       ra.setSize(400, 300);       ra.setVisible(true);     }       public RowAdder() {       final JTextField textField  = new JTextField();       setLayout(new BorderLayout());       add(new JScrollPane(table), BorderLayout.CENTER);       textField.addActionListener(new ActionListener() {         public void actionPerformed(ActionEvent event) {           tableData.addText(textField.getText());           textField.setText("");         }       });       add(textField, BorderLayout.SOUTH);     }     }   class SimpleModel extends AbstractTableModel {       Vector textData = new Vector();       public void addText(String text) {       textData.addElement(text);       fireTableDataChanged();     }       public int getRowCount() {       return textData.size();     }       public int getColumnCount() {       return 3;     }       public Object getValueAt(int row, int column) {       return textData.elementAt(row);     }     }
