Hey just add Cell Renderer and Editor also...
TableColumn col = table.getColumnModel().getColumn(0);
col.setCellRenderer(new CheckBoxRenderer());
col.setCellEditor(new CheckBoxEditor(new JCheckBox()));
public class CheckBoxRenderer extends JCheckBox implements TableCellRenderer
private static final long serialVersionUID = 1L;
CheckBoxRenderer()
super();
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column)
if (value == null)
return null;
return (Component) value;
public class CheckBoxEditor extends DefaultCellEditor implements ItemListener
private static final long serialVersionUID = 1L;
private JCheckBox button;
protected Border columnBorder;
public CheckBoxEditor(JCheckBox checkBox)
super(checkBox);
public Component getTableCellEditorComponent(JTable table, Object value,
boolean isSelected, int row, int column)
if (value == null)
return null;
button = (JCheckBox) value;
button.addItemListener(this);
return (Component) value;
public Object getCellEditorValue()
button.removeItemListener(this);
return button;
public void itemStateChanged(ItemEvent e)
super.fireEditingStopped();
}
