Thanks Matt!
I've succeed in changing JTable behaviour. This is an extract of my
solution:

public class Frame1 extends JFrame {

  TableModel1 myModel = new TableModel1();
  JTable jTable1 = new JTable(myModel); // Create the table with your
own model.
  [...]

  public Frame1() {
    setUpColorRenderer(jTable1); // Change the Table render for Labels
with Color.
    [...]
  } 
  
  [...]

  class TableModel1 extends AbstractTableModel {
    Object[][] data = null; // This are the labels with different
colors.
    [...]

    public TableModel1(){
           [...]
           data = new Object[Max][1];
           for(int i=1;i<= Max;i++){
             TextWithBckg text= new TextWithBckg(" "+i+"
",Color.lightGray);
             data[i-1][0]=(Object)text;                 
           }
    }
    [...]
  }   

class ColorRenderer extends JLabel implements TableCellRenderer {
  Border unselectedBorder = null;
  Border selectedBorder = null;
  boolean isBordered = true;

  public ColorRenderer(boolean isBordered) {
            super();
	          this.isBordered = isBordered;
            setOpaque(true); //MUST do this for background to show up.
    }
        
    public Component getTableCellRendererComponent(
                                JTable table, Object b, 
                                boolean isSelected, boolean hasFocus,
                                int row, int column) {
    if (b!=null){
      TextWithBckg data=(TextWithBckg)b;
      setText(data.text);
      setHorizontalAlignment(com.sun.java.swing.SwingConstants.RIGHT);
      setBackground(data.color);
    }
      if (isBordered) {
       if (isSelected) {
		    if (selectedBorder == null) {
		        selectedBorder = BorderFactory.createMatteBorder(2,5,2,5,
                                                 
table.getSelectionBackground());
		    }
        setBorder(selectedBorder);
	     } else {
		    if (unselectedBorder == null) {
		        unselectedBorder = BorderFactory.createMatteBorder(2,5,2,5,
                                                 
table.getBackground());
		    }
        setBorder(unselectedBorder);
	     }
      }
      
      return this;
    }
}

}

class TextWithBckg {

  String text;
  Color color;

  public TextoConfondo(String t, Color c){
    text=t;
    color=c;
  }  
}


And that's all necessary changes. Please, note that this is just an
extract and must be completed with all necessary methods. The URL
http://java.sun.com/docs/books/tutorial/ui/swing/table.html contains all
hints to do it.
