To render those cells with an underline have your TableCellRenderer return a JTextPane set up as follows:
// Do this once somewhere
SimpleAttributeSet hyperlinkStyle = new SimpleAttributeSet();
StyleConstants.setForeground(hyperlinkStyle, Color.BLUE);
StyleConstants.setUnderline(hyperlinkStyle, true);
public class MyRenderer implements TableCellRenderer
JTextPane hyperlinkRenderer = new JTextPane();
public Component getTableCellRendererComponent(JTable table,
                                               Object value,
                                               boolean isSelected,
                                               boolean hasFocus,
                                               int row,
                                               int column)
  // When its a hyperlink cell do something like...
  hyperlinkRenderer. setText("");
  //  ...assuming toString is OK for you
  hyperlinkRenderer.getDocument().insertString(0, hyperlinkStyle, value.toString());
  return hyperlinkRenderer;
}and for the mouse cursor add a MouseMotionListener to your JTable and implement mouseMoved(MouseEvent e). Then
Point p = event.getPoint();
// Locate the model coordinates under the event location
int hitColumnIndex = columnAtPoint(p);
int hitRowIndex = rowAtPoint(p);
if (its a hyperlink cell)
  myJTable.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
else
  myJTable.setCursor(Cursor.getDefaultCursor());
}You can either do the click with a MouseListener or by cell selection events, if that is OK.
Hope that helps - good luck.
