基本上我想做的是，我有一个包含可用驱动器列表的 JList，如果用户选择了其中一个驱动器，那么我将显示位于 JTable 中选定驱动器中的所有 html 文件，所以我放了一个事件我的 JList 的侦听器，然后我创建一个 JTable 并将所有数据放在那里并将其显示在容器中。代码如下所示：

static class HtmlListing implements ListSelectionListener
        {
            public void valueChanged(ListSelectionEvent event) 
            {
              if (!event.getValueIsAdjusting())
              {   //trying to remove and re-add controls in container.
                  EastCont.removeAll(); 

                  globarr = new ArrayList<File>(); // global variable

                  FileListing fl = new FileListing();
                  fl.walk(fileList1.getSelectedValue() + "work\\airasia\\html", 500, 0);    

                  //if(globarr.size() > 0)
                  //{
                       Object[][] data = new Object[globarr.size()][globarr.size()];

                       for(int i = 0; i < globarr.size(); i++)
                       {
                           if(globarr.get(i).isFile())
                           {
                               String filename =  globarr.get(i).getName().toString();
                               String date = sdf.format(globarr.get(i).lastModified());

                               Object[] obj = new Object[] {filename,  filename.substring(filename.lastIndexOf(".") + 1), date, globarr.get(i).getAbsolutePath()};
                               data[i] = obj;
                           }
                       }

                      Object[] column = new Object[]{"name ", "type", "date modified", "path"}; 

                      DefaultTableModel model = new DefaultTableModel(data, column);
                      model.fireTableDataChanged();

                       table =  new JTable(model) 
                       {
                            private static final long serialVersionUID = 1L;

                            public boolean isCellEditable(int row, int column) 
                            {                
                                    return false;               
                            };  
                        };

                       table.addMouseListener(new MouseAdapter()
                       {
                             public void mouseClicked(MouseEvent e)
                             {
                                  if (e.getClickCount() == 2)
                                  {
                                      int rowIdx = table.getSelectedRow(); // path to your new file
                                      TableModel tm = table.getModel();
                                      String path =  tm.getValueAt(rowIdx, 3).toString(); 
                                      File htmlFile = new File(path);

                                      try // open the default web browser for the HTML page
                                      {
                                          Desktop.getDesktop().browse(htmlFile.toURI());
                                          //Desktop.getDesktop().open(htmlFile);
                                      } 
                                      catch (IOException e1) 
                                      {
                                            // TODO Auto-generated catch block
                                            e1.printStackTrace();
                                      }
                                  }
                             }
                        });

                       table.removeColumn(table.getColumnModel().getColumn(3)); //hide column path from display
                       table.setFillsViewportHeight(true);
                       table.setIntercellSpacing(new Dimension(0, 5));
                       table.setShowGrid(false);

                       scrollPane = new JScrollPane(table);

                       EastCont = new JPanel();
                       EastCont.setLayout(new BorderLayout());
                       EastCont.add(scrollPane);
                       EastCont.setPreferredSize(new Dimension(1050, 1000));

                       //EastCont.repaint();
                       //EastCont.revalidate();

                       gui.add(EastCont, BorderLayout.EAST);
                       gui.revalidate();
                       gui.repaint();  
                // }
                // else                
                // {
                //     EastCont.remove(table);
                //     gui.remove(EastCont);
                //     gui.revalidate();
                //     gui.repaint();
                // } 
            }

此代码仅适用于第一次，但不适用于第二次等等，所以我在这里想念什么？任何帮助都会很棒。谢谢你。

DefaultTableModel model = new DefaultTableModel(data, column);
//model.fireTableDataChanged();
//table =  new JTable(model) 
table.setModel( model );

Don't create a new table change reset the model of your current table. The rest of the code in that method is not necessary either since you are not creating any new GUI components.

Also, never invoke a fireXXX method. That is the responsibility of the TableModel.
