【问题描述】：
我正在开发一个自定义搜索组件。单击文本字段内的按钮（搜索图像图标）时，将显示一个表格。代码处于非常初级的阶段，所以很多东西都不存在。
到目前为止，我被卡住了，因为我无法使用箭头键导航表格。一旦我在表格中选择了一行，我也无法使用“tab”键移动到下一个文本字段。
该组件的目标是从表中选择一行，然后在支持方法（尚未编写）的帮助下，将默认来自其他标签和文本字段的值，同时默认文本中的第一列值它附加到的字段。
非常感谢您的帮助。谢谢！！

【问题讨论】：
-
@AndrewThompson - 它在那里..
-
对不起（flamewar）你的录取率保护了我一切，祝你好运，新年快乐
-
@HovercraftFullOfEels - 我是否需要为 JTable 编写密钥发布代码。 JTable 在 BasicTableUI 中默认有这个。
-
我之前也接受了你的回答。只是因为个人问题，我现在休息了很长时间。所以没有检查以前的帖子和答案。 PLz帮助大家！！

“所以没有检查以前的帖子和答案。” 现在是查看past questions 的好时机。 :)
