Java Swing JTable（表格单元格编辑器/渲染器问题）

问：

我找不到问题发生的原因。

我的程序有 3 个 JTables，其中创建为 JLabel 的按钮将调用特定方法。

当我传递 TblBotao 对象时，问题发生了，但是当它们在 JPanel 构造函数中实例化时，问题不会发生。

你能帮我告诉我我的代码有什么问题吗？

public interface IClique {
    void clicar();
}

public class TblBotao extends JLabel {
    public TblBotao(String titulo, String icone, IClique clique) {

        setOpaque(false);
        setToolTipText(titulo);
        setIcon(new FlatSVGIcon(icone, 14, 14));
        setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));

        addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent e) {
                clique.clicar();
            }
        });

    }

}

//How objects are instantiated.
final var BOTOES = new TblBotao[] {
        new TblBotao("Editar", "img/icons/util/edit.svg", new IClique() {
            @Override
            public void clicar() {
                gerenciarCliente(TipoAcao.EDITAR);
            }
        }),
        new TblBotao("Apagar", "img/icons/util/delete.svg", new IClique() {
            @Override
            public void clicar() {
                gerenciarCliente(TipoAcao.APAGAR);
            }
        })
};

//Adding the buttons
int col = tblCliente.getColumnCount() - 1;

tblCliente.getColumnModel().getColumn(col).setCellRenderer(new TblCelulaRenderer(BOTOES));
tblCliente.getColumnModel().getColumn(col).setCellEditor(new TblCelulaEditor(BOTOES));

public class TblPanel extends JPanel {

    public TblPanel(TblBotao[] botoes) {

        setLayout(new FlowLayout(FlowLayout.CENTER, 5, 0));

        // This way there are problems.
        for (TblBotao botao : botoes) {
            add(botao);
        }

       // So there's no problem
       //add(new TblBotao("Editar", "img/icons/util/edit.svg", null));
       //add(new TblBotao("Apagar", "img/icons/util/delete.svg", null));

    }

    @Override
    public boolean isFocusable() {
        return false;
    }

}


public class TblCelulaRenderer extends DefaultTableCellRenderer {
    private final TblBotao[] botoes;
    public TblCelulaRenderer(TblBotao[] botoes) {
        this.botoes = botoes;
    }

    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {

        Component c = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);

        TblPanel panel = new TblPanel(botoes);
        panel.setBackground(isSelected ? table.getSelectionBackground() : c.getBackground());

        return panel;

    }
}

public class TblCelulaEditor extends DefaultCellEditor {
    private final TblBotao[] botoes;
    public TblCelulaEditor(TblBotao[] botoes) {
        super(new JTextField());
        this.botoes = botoes;
    }

    @Override
    public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) {

        TblPanel panel = new TblPanel(botoes);
        panel.setBackground(table.getSelectionBackground());
        setClickCountToStart(1);

        return panel;
    }

}

查看 2 种表单的行为，包括有问题和没有问题。

// In the constructor of the TblPanel class, if it is 
// used this way, the problem with the first animation happens.

for (TblBotao botao : botoes) {
    add(botao);
}

// Now if it is implemented this way, the problem does not happen, 
// and it works perfectly, as in the second animation.

add(new TblBotao("Editar", "img/icons/util/edit.svg", null));
add(new TblBotao("Apagar", "img/icons/util/delete.svg", null));

当选择单元格时，内容消失了，这是怎么回事？ 我无法理解，因为当在 JPanel 构造函数中实例化时，它们正常工作。
