如何在合并的单元格中不显示网格线

Question

我的JavaFX窗口中有GridPane，我有两列。

当我点击在scenebuilder中可见的网格线时，合并单元格中间有一条线。

如何删除或不显示此行？

Answer 1

这是一种方法：在这种方法中，我将GridPane's背景设为黑色。然后我拉伸每个Node以填充他们的Cell并使Node's背景变为白色。同样在GridPane上，我将所有Insets设置为5，将VGap和HGap设置为5. 我建议您使用CSS并采取@ James_D的方法here。

  

FXML：

<?import javafx.geometry.Insets?>
<?import javafx.scene.control.Label?>
