Java 如何在JTable中将JRadioButton添加到组中
我使用渲染器和编辑器将单选按钮添加到Java 如何在JTable中将JRadioButton添加到组中,java,swing,jtable,jradiobutton,buttongroup,Java,Swing,Jtable,Jradiobutton,Buttongroup,我使用渲染器和编辑器将单选按钮添加到JTable。我还为同一个项目创建了一个组。我无法使用此原则实现排他性（只能选择一个单选按钮）。请参阅下面我的代码，并感谢您的回复 渲染器和编辑器类： class RadioButtonRenderer implements TableCellRenderer { public Component getTableCellRendererComponent(JTable table, Object value, boolean
