我要在窗口调整大小时调整像JTable这样的少量元素。我一直在尝试这段代码,但它无法正常工作:
table.setLocation(0, 23);
Dimension siz = contentPane.getMaximumSize();
table.setSize(siz.height, siz.width - 46);
它调整了我的桌子大小,但它让它变得无穷无尽,我不想要它。另外,我想将滚动条连接到此表,如果可能的话 - 在precentage中设置列宽

您的主要问题(调整大小)更多地与您依赖表单编辑器有关,而与Swing或Java有关
有关详细信息,请查看Laying Out Components Within a Container。
您似乎也没有使用JScrollPane
来容纳JTable
。请查看How to Use Tables和How to Use Scroll Panes了解更多详情
