JTable排序不顯示圖像

Question

因此，我已成功實現了一個搜索功能到我的小程序，但當我點擊按鈕進行排序，它工作正常，但圖像不顯示。這是我爲分揀機添加的代碼，它工作正常，但每行的圖像都不顯示。當我拿出這段代碼時，圖像顯示出來，但排序不起作用。有沒有可以在排序時顯示圖像？

// Sorter Code. Images show up when this code gets taken out. 
    table = new JTable(model); 
    final TableRowSorter<TableModel> sorter = new TableRowSorter<TableModel>(model); 
    table.setRowSorter(sorter); 
    search_button.addActionListener(new ActionListener() { 
     public void actionPerformed(ActionEvent e) { 
      String text = search.getText(); 
      if (text.length() == 0) { 
      sorter.setRowFilter(null); 
      } else { 
      sorter.setRowFilter(RowFilter.regexFilter(text)); 
      } 
     } 
     }); 
    // sorter code ends here.

• 必須與它的模型同步JTable看來，

• 已經看清楚方法convertXxxIndexToXxx

• 添加int modelRow = convertRowIndexToModel(row);您Renderer或prepareRenderer

• example convertRowIndexToModel
