Java使用自定义的tableModel，设置可编辑方式：

package com.han;

import java.awt.BorderLayout;
import java.util.Vector;

import javax.swing.JFrame;

/**
 * Provide a fixed column in a table.
 *
 * <code><p>public boolean isCellEditable(int row, int column) {<p>
        return getModel().isCellEditable(convertRowIndexToModel(row),<p>
                                         convertColumnIndexToModel(column));<p>
    }<p>
    </code>
 *  so we can also directly rewrite the isCellEditable() in the table model.
