private final DefaultTableModel model = new DefaultTableModel();
private final JTable table;

private void createActionPerformed(ActionEvent e) {
  int rc = model.getRowCount();
  model.addRow(new Object[] {rc, "New name", ""});
  // 追加された最終行までスクロール
  table.scrollRectToVisible(table.getCellRect(rc, 0, true));
}

private void deleteActionPerformed(ActionEvent e) {
  int[] selection = table.getSelectedRows();
  for (int i = selection.length - 1; i >= 0; i--) {
    model.removeRow(table.convertRowIndexToModel(selection[i]));
  }
}
