在我的jFrame中，我创建了一个包含患者的表格。列表和一个允许刷新操作表的按钮。当我点击第一次刷新按钮时，列表将显示在表格中。然而，当我第二次按下它时，它不再工作，表格也无法刷新。 对这个问题有什么想法吗？ 这是刷新按钮的代码：
public class Interface extends javax.swing.JFrame{
private void RefreshActionPerformed(java.awt.event.ActionEvent evt) {
DefaultTableModel model = (DefaultTableModel)worklisttable.getModel();
int rowCount = model.getRowCount();
for (int i = rowCount - 1; i >= 0; i--) {
model.removeRow(i);
}
model.fireTableDataChanged();
GetMwl_3.main(args);
}

......
