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

了解更多信息。我得到了同样的例外。我发现我需要调用＆＃34; setCellValueFactory＆＃34;设置TableColumn实例时的方法。我错误地打电话给＃34; setCellFactory＆＃34;。

您可以尝试以下链接，它可以正常工作。如需进一步的帮助，您必须提供代码。 Populate a tableview using database in JavaFX

由于您要指定如何填充列的值，因此请务必使用setCell 值工厂方法。
