無法使用CustomTableModel將JButton添加到JTable中

Question

我正在使用擴展AbstractTableModel的CustomTableModel創建表。我無法將JButton添加到使用此自定義模型的列中。如果我對模型執行新的JButton（「One」）..我看到文本「javax.swing.JButton [，0 ....，defaultCapable = true]」而不是按鈕。任何幫助讚賞。

public class CustomModelForTable extends AbstractTableModel { 

/** 
* 
*/ 
private static final long serialVersionUID = 1L; 

private String[] columnNames = {"First Name", 
     "Last Name", 
     "Sport", 
     "# of Years", 
     "Vegetarian", 
     "Button"}; 

private Object[][] data = { 
          {"Kathy", "Smith", "Snowboarding", new Integer(5), new Boolean(false), new JButton("One")}, 
          {"John", "Doe", "Rowing", new Integer(3), new Boolean(true), new JButton("Two")}, 
          {"Sue", "Black", "Knitting", new Integer(2), new Boolean(false), new JButton("three")}, 
          {"Jane", "White", "Speed reading", new Integer(20), new Boolean(true), new JButton("Four")}, 
          {"Joe", "Brown", "Pool", new Integer(10), new Boolean(false), new JButton("Five")} 
          }; 

// # of Rows; 
public int getRowCount() { 
    return data.length; 
} 

// # of Columns; 
public int getColumnCount() { 
    return columnNames.length; 
} 

public Object getValueAt(int rowIndex, int columnIndex) { 
    return data[rowIndex][columnIndex]; 
} 

public Class getColumnClass(int column) { 
    return getValueAt(0, column).getClass(); 
} 

public boolean isCellEditable(int rowIndex, int columnIndex) { 
    return true; 
} 

public void setValueAt(Object value, int rowIndex, int columnIndex) { 
    if(isCellEditable(rowIndex, columnIndex)) { 
     data[rowIndex][columnIndex] = value; 
    } 
} 
} 

編輯： 我能夠實現的TableCellRenderer添加的JButton。謝謝大家。

通過實現TableCellRenderer我可以添加按鈕到表中。

class CustomModelForTable extends AbstractTableModel { 
// Code 
// After creating table using model. 

TableCellRenderer defaultRenderer = tableA.getDefaultRenderer(JButton.class); 
    tableA.setDefaultRenderer(JButton.class, new  JButtonRendererClass(defaultRenderer)); 
// Code 
} 


class JButtonRendererClass implements TableCellRenderer { 

private TableCellRenderer __defaultRenderer; 

public JButtonRendererClass(TableCellRenderer myRenderer) { 
    __defaultRenderer = myRenderer; 
} 

public Component getTableCellRendererComponent(JTable table, Object value, 
     boolean isSelected, boolean hasFocus, int row, int column) { 
    if(value instanceof Component) { 
     return (Component) value; 
    } 
    return __defaultRenderer.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column); 
} 
} 

認爲它可能對某人有用。
