Hartmut,

I can reproduce your problem now. I guess John was right,
scrollRectToVisible fails because the necessary repaint happens after the
fact.

So invokeLater will do it, although I still consider it a hack.

    int count = 400;
    String[][] data = new String[count][3];
    for (int i = 0; i < count ; i++) {
      data[i][0] = "A_" + i;
      data[i][1] = "B_" + i;
      data[i][2] = "C_" + i;
    }
    String[] columns = {"Field_A", "Field_B", "Field_C"};
    table.setModel(new javax.swing.table.DefaultTableModel(data, columns));
    SwingUtilities.invokeLater(new Runnable() {
      public void run() {
        scroller.getViewport().scrollRectToVisible(
table.getCellRect(table.getRowCount(), 0, true ) );
      }
    });

Please note that your removeRow/addRow approach is pretty inefficient, it's
much faster to set up the whole model "outside the table" and then to hand
it to the table in one shot. You don't even have to remove the old rows this
way.
