自定義表格原始對象

Question

作爲項目的一部分，我希望爲每個單元製作不同類型對象的表格，但我無法理解如何使每個單元格都自定義......我發現here如何設置列它有一個像String，Bool，Slider這樣的對象類型......但是對於每個Cell我都不知道！

這幅畫是從jformDesigner軟件性能的一部分，我想是這樣的表：

這個例子可以作爲一個起點：

import java.awt.*; 
import java.util.*; 
import javax.swing.*; 
import javax.swing.event.*; 
import javax.swing.table.*; 

public class TablePropertyEditor extends JFrame 
{ 
    public TablePropertyEditor() 
    { 
     String[] columnNames = {"Type", "Value"}; 
     Object[][] data = 
     { 
      {"String", "I'm a string"}, 
      {"Date", new Date()}, 
      {"Integer", new Integer(123)}, 
      {"Double", new Double(123.45)}, 
      {"Boolean", Boolean.TRUE} 
     }; 

     JTable table = new JTable(data, columnNames) 
     { 
      private Class editingClass; 

      public TableCellRenderer getCellRenderer(int row, int column) 
      { 
       editingClass = null; 
       int modelColumn = convertColumnIndexToModel(column); 

       if (modelColumn == 1) 
       { 
        Class rowClass = getModel().getValueAt(row, modelColumn).getClass(); 
        return getDefaultRenderer(rowClass); 
       } 
       else 
        return super.getCellRenderer(row, column); 
      } 

      public TableCellEditor getCellEditor(int row, int column) 
      { 
       editingClass = null; 
       int modelColumn = convertColumnIndexToModel(column); 

       if (modelColumn == 1) 
       { 
        editingClass = getModel().getValueAt(row, modelColumn).getClass(); 
        return getDefaultEditor(editingClass); 
       } 
       else 
        return super.getCellEditor(row, column); 
      } 

      // This method is also invoked by the editor when the value in the editor 
      // component is saved in the TableModel. The class was saved when the 
      // editor was invoked so the proper class can be created. 

      public Class getColumnClass(int column) 
      { 
       return editingClass != null ? editingClass : super.getColumnClass(column); 
      } 
     }; 

     table.setPreferredScrollableViewportSize(table.getPreferredSize()); 
     JScrollPane scrollPane = new JScrollPane(table); 
     getContentPane().add(scrollPane); 
    } 

    public static void main(String[] args) 
    { 
     TablePropertyEditor frame = new TablePropertyEditor(); 
     frame.setDefaultCloseOperation(EXIT_ON_CLOSE); 
     frame.pack(); 
     frame.setLocationRelativeTo(null); 
     frame.setVisible(true); 
    } 
}
