Java-Jtable-不同颜色的单元格

我已经看到了一些例子，但仍然无法理解如何解决这个问题，可能没有一个干净的解决方案。。 我试图通过使用10*10作为单元格的Jtable来构建John Conway的生命游戏。我知道如何更改表格背景颜色（所有单元格），但我无法更改特定单元格的颜色。我知道，我需要用CellRenderer创建一个类，但我也无法理解它

这是我的密码：

public class theGame {

    public static void main(String [] args) {

        theMatrix gui = new theMatrix();

        gui.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        gui.setSize(550,450);
        gui.setVisible(true);
        gui.setTitle("Game Of Life");



        JOptionPane.showMessageDialog(null, "  Welcome John Conway's Game Of Life  ");
        int replay = JOptionPane.showConfirmDialog(null, "Would you like to see the next generation?", "Close?", JOptionPane.YES_NO_OPTION);

        if (replay == JOptionPane.YES_OPTION);

    }
}

下面是一个自定义单元渲染的示例，它根据行和列更改背景颜色：

public class TheMatrix extends JFrame {

    JTable table;

    public TheMatrix() {
        setLayout(new FlowLayout());
        String[] columNames = {"", "", "", "", "", "", "", "", "", ""};

        Object[][] data = { // Create a 10*10 table with default values.

            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null}
        };

        table = new JTable(data, columNames);
        table.setPreferredScrollableViewportSize(new Dimension(500, 500));
        table.setRowHeight(40);
        table.setDefaultRenderer(Object.class, new MyRenderer());

        JScrollPane scrollPane = new JScrollPane(table);
        add(scrollPane);
    }
}

class MyRenderer implements TableCellRenderer {

    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected,
                                    boolean hasFocus, int row, int col) {
        JTextField cell = new JTextField();

        cell.setBackground(((row % 2) == 0) && ((col % 2) == 0) ? Color.WHITE : Color.BLACK);
        return cell;
      }
}

单元格渲染器应该使用特定单元格的数据来确定如何渲染。当然，我会将表格更改为0,1，然后尝试按游戏应该的不同类型对其着色。如何更改颜色？什么颜色有什么价值？并始终在问题中显示您的最佳尝试代码，以创建更好的问题并获得更好的帮助。谢谢！我想我知道如何借助这个答案来解决这个问题--

public class TheMatrix extends JFrame {

    JTable table;

    public TheMatrix() {
        setLayout(new FlowLayout());
        String[] columNames = {"", "", "", "", "", "", "", "", "", ""};

        Object[][] data = { // Create a 10*10 table with default values.

            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null},
            {null, null, null, null, null, null, null, null, null, null}
        };

        table = new JTable(data, columNames);
        table.setPreferredScrollableViewportSize(new Dimension(500, 500));
        table.setRowHeight(40);
        table.setDefaultRenderer(Object.class, new MyRenderer());

        JScrollPane scrollPane = new JScrollPane(table);
        add(scrollPane);
    }
}

class MyRenderer implements TableCellRenderer {

    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected,
                                    boolean hasFocus, int row, int col) {
        JTextField cell = new JTextField();

        cell.setBackground(((row % 2) == 0) && ((col % 2) == 0) ? Color.WHITE : Color.BLACK);
        return cell;
      }
}
