Thanks for the hints on how to do this. I elaborated a little on it trying to get rid of the TableColumn. I aldready had a subclass of DefaultTableCellRenderer doing some custom coloring in getTableCellRendererComponent(). I could extend this method for doing the tooltip stuff - see this stripped down version:

public class TableCellRendererMy extends DefaultTableCellRenderer implements TableCellRenderer {

  public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
      super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
      
      double cellPrefWidth = getPreferredSize().getWidth();
      double cellWidth= table.getCellRect(row, column, false).getWidth();
      
      if (cellPrefWidth>cellWidth) {
        try {
            setToolTipText(String.valueOf(value));
        } catch (Exception e) {
        }
      }
      
      return this;
  }
}

regerds,
stephan
