Comment rendre une case à cocher dans un JTable?

C'est mon code afin de le rendre un JTable et changer la couleur des lignes, mais il ne montre pas une case à cocher dans la colonne 6, seule chaîne (vrai,faux).

Pouvez-vous fournir une solution pour résoudre ce problème?

Merci d'avance.

    public class JLabelRenderer extends JLabel implements TableCellRenderer
{
  private MyJTable myTable;
  /**
   * Creates a Custom JLabel Cell Renderer
   * @param t your JTable implmentation that holds the Hashtable to inquire for
   * rows and colors to paint.
   */
  public JLabelRenderer(MyJTable t)
  {
    this.myTable = t;
  }

  /**
   * Returns the component used for drawing the cell.  This method is
   * used to configure the renderer appropriately before drawing.
   * see TableCellRenderer.getTableCellRendererComponent(...); for more comments on the method
   */
  public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
  {
    setOpaque(true); //JLabel isn't opaque by default

    setText(value.toString());
    setFont(myTable.getFont());

    if(!isSelected)//if the row is not selected then use the custom color
    setBackground(myTable.getRowToPaint(row));
    else //if the row is selected use the default selection color
    setBackground(myTable.getSelectionBackground());

    //Foreground could be changed using another Hashtable...
    setForeground(myTable.getForeground());

    //Since the renderer is a component, return itself
    return this;
  }

  //The following methods override the defaults for performance reasons
  public void validate() {}
  public void revalidate() {}
  protected void firePropertyChange(String propertyName, Object oldValue, Object newValue) {}
  public void firePropertyChange(String propertyName, boolean oldValue, boolean newValue) {}
}

C'est la table:

import javax.swing.JTable;    
import javax.swing.table.*;
import java.util.Hashtable;
import java.awt.Color;
public class MyJTable extends JTable
{
Hashtable rowsToPaint = new Hashtable(1);
/**
* Default Constructor
*/
public MyJTable()
{
super();
}
/**
* Set the TableModel and then render each column with a custom cell renderer
* @param tm TableModel
*/
public void setModel(TableModel tm)
{
super.setModel(tm);
renderColumns(new JLabelRenderer(this));
}
/**
* Add a new entry indicating:
* @param row the row to paint - the first row = 0;
* @param bgColor background color
*/
public void addRowToPaint(int row, Color bgColor)
{
rowsToPaint.put(new Integer(row), bgColor);
this.repaint();//you need to repaint the table for each you put in the hashtable.
}
/**
* Returns the user selected BG Color or default BG Color.
* @param row the row to paint
* @return Color BG Color selected by the user for the row
*/
public Color getRowToPaint(int row)
{
Color bgColor = (Color)rowsToPaint.get(new Integer(row));
return (bgColor != null)?bgColor:getBackground();
}
/**
* Render all columns with the specified cell renderer
* @param cellRender TableCellRenderer
*/
public  void renderColumns(TableCellRenderer cellRender)
{
for(int i=0; i<this.getModel().getColumnCount(); i++)
{
renderColumn(this.getColumnModel().getColumn(i), cellRender);
}
}
/**
* Render a TableColumn with the sepecified Cell Renderer
* @param col TableColumn
* @param cellRender TableCellRenderer
*/
public void renderColumn(TableColumn col, TableCellRenderer cellRender)
{
try{
col.setCellRenderer(cellRender);
}catch(Exception e){System.err.println("Error rendering column: [HeaderValue]: "+col.getHeaderValue().toString()+" [Identifier]: "+col.getIdentifier().toString());}
}
}
