在我从数据结构中的excel导入电子表格的名称之后，我尝试用fireTableChanged()方法更新我的fireTableChanged，但是该方法没有被执行。我通过测试确认数据是正确导入的，jtable应该有必要的信息。

如果JTable被正确更新，我需要做什么？我找到了其他几个关于这个话题的链接，但没有一个对我有用：

刷新Jtable

如何在更新数据库后使JTable显示刷新的数据？

JTable如何在插入、删除或更新数据后刷新表模型。

AbstractDataTable fireTableDataChanged()不刷新jtable

不能用新数据刷新JTable

型号：

public class Model extends Observable {
String[][] data;
List<Arbeitsmappe> AMList = new LinkedList<>();
.....
public void setAMList(List<Arbeitsmappe> aMList) {
AMList = aMList; //new List replace the old
this.getData(); //The 2dimensional Array is filled with the names from the list
setChanged(); 
notifyObservers(Controller.Command_Excel_Eingelesen);
}

查看：

    JTextField cellEditorTF = new JTextField();
    cellEditorTF.setEditable(false);
    DefaultCellEditor cellEditor = new DefaultCellEditor(cellEditorTF);
    ContentTable = new JTable(model.getData(), Model.columnNames);
    //Cell Editable FALSE
    ContentTable.getColumnModel().getColumn(0).setCellEditor(cellEditor);
    //Single Interval Selection 
    ContentTable.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);
    //Cell Listener - When Cell is edited the new informationen is safed in AMLISt
    Action action = new AbstractAction()
        public void actionPerformed(ActionEvent e)
            TableCellListener tcl = (TableCellListener)e.getSource();
            Model.AMList.get(tcl.getRow()).Speichername = String.valueOf(tcl.getNewValue());
           // System.out.println("Row: " + tcl.getRow() + "  " + Model.data[tcl.getRow()][1]);
    TableCellListener tcl = new TableCellListener(ContentTable, action);
    JScrollPane scrollPane = new JScrollPane(ContentTable);
    ContentTable.setFillsViewportHeight(true);
    ContentTable.getTableHeader().setReorderingAllowed(false);
    this.add(BorderLayout.NORTH,ButtonPanel);
    this.add(BorderLayout.SOUTH,scrollPane);
@Override
public void update(Observable arg0, Object arg1) {
    if(arg0 instanceof Model){
        Model model = (Model) arg0;
        String cmd = (String) arg1;
        if(cmd.equals(Controller.Command_Excel_Eingelesen)){
