这些变得非常棘手。我认为任何与“行为相关”的东西（即对用户输入做出反应的标准控件）都很难更改，并且JavaFX通常不提供很好的支持。希望这是API的一个可以改进的地方…

似乎有几个不同的问题。我认为Enter键发生的事情是，尽管这会ActionEvent在文本字段上生成一个，并提交编辑等，但该keyTyped事件仍会传播回表，从而使其重新进入编辑模式。解决此问题的方法似乎是keyPressed在表上使用处理程序（尽管老实说这并不十分健壮）。

该代码依赖于onEditCommit表列上的默认处理程序来实际更改属性值。该onEditCommit处理程序由默认表单元格的commitEdit方法调用。调用commitEdit(...)时失去焦点的问题在于，默认commitEdit方法首先检查单元格是否处于编辑状态，否则将不执行任何操作。似乎当单元格失去焦点时，在focusProperty调用侦听器之前将其移出编辑状态，因此onEditCommit永远不会调用该处理程序。（顺便说一句，这也使示例13-11“单元格编辑的替代解决方案”（原文如此）无法在JDK
8 u25（当前版本）中正常工作。）

对于第二个问题，我看到的唯一解决commitEdit(...)方法是直接从方法中更新属性。这要求单元格具有对该属性的引用，这破坏了单元格与单元格值之间的良好分隔。

我使用通常的Person示例重写了该示例，并合并了这两个修复程序。尽管我说过某些部分似乎并不十分健壮，但该示例仍然运行良好：
