推荐答案
如果您使用的是Netbeans，则可以使用GUI Builder.只需转到设计视图"，右键单击要用于此的基础容器(某些JPanel)，转到上下文菜单中的设置布局"选项，然后选择网格布局".要编辑其属性，请转到导航器"窗口(通常在左侧)，浏览组件，直到看到有问题的容器，将其折叠并选择GridLayout.现在，您可以在属性窗口(通常在右侧)上更改某些属性，例如行和列.然后，将其他组件拖动到该容器的顶部.
If you're using Netbeans, you can do that with the GUI Builder. Simply go to the Design View, right click on the underlying container you're going to use for this (some JPanel), go to "Set Layout" option in the context menu and pick "Grid Layout". To edit its properties, go to the Navigator window (usually on the left), browse your components until you see the container in question, collapse it and select the GridLayout. You can now change some properties, like the rows and columns, on the properties window (usually on the right). Then, you drag other components on top of that container.
但是，根据您的描述，我想知道您真正要查找的是 JTable ，该组件可让您在网格中显示数据.
Though, by your description, I wonder if what you're really looking for is a JTable, which is a component that lets you display your data in a grid.
