以编程方式在JTable中select一行

当应用程序启动时，没有任何行被选中。 但是我想表明第一行已经被选中。

这个怎么做？ 我需要在JTable设置一行的颜色吗？

更新：我试过table.setRowSelectionInterval（0,0）。 我知道它应该工作，但有一个错误消息：

你可以这样做，调用setRowSelectionInterval ： 

 table.setRowSelectionInterval(0, 0);

select第一行。

这是一个旧的post，但我最近碰到这个

select特定的时间间隔

正如@aleroot已经提到的那样，通过使用 

 table.setRowSelectionInterval(index0, index1);

您可以指定应该select的时间间隔。

将间隔添加到现有的select

您也可以保留当前的select，并在这里使用这个简单地添加额外的行 

 table.getSelectionModel().addSelectionInterval(index0, index1);

这行代码还会select指定的时间间隔。 这个时间间隔是否已经被选中并不重要，其中的一部分被选中。

您使用JTable的可用API ，不要试图混淆颜色。

有些select方法可直接在JTable （如setRowSelectionInterval ）。 如果你想访问所有与select有关的逻辑， select模型是开始寻找的地方
