我是 JavaFX 的新手。我正在使用 TableView 并尝试将用户从用户名和密码字段输入的数据放入表中。它只是一个测试程序。我收到以下错误。

SEVERE: javafx.scene.control.Control loadSkinClass Failed to load skin 'StringProperty [bean: TableRow[id=null, styleClass=cell indexed-cell table-row-cell], name: skinClassName, value: com.sun.javafx.scene.control.skin.TableRowSkin]' for control TableRow[id=null, styleClass=cell indexed-cell table-row-cell]

有关一些其他信息。我得到了同样的例外。我发现在设置 TableColumn 实例时需要调用“setCellValueFactory”方法。我错误地调用了“setCellFactory”。

由于您要指定如何填充列的值，因此请确保使用 setCell值工厂方法。
