java - making a jtable bigger to fit all data

Question

I currently have a JTable inside a JscrollPane inside a JPanel. No matter what I set the size of either of those 3 elements, the table always shows up as the same size. The JPanel is in BorderLayout and I am packing the frame. the reason I want to do this is because some of the data in my columns doesn't fit without having to make other columns way too small.

Answer 1

• 覆盖table.getPreferredScrollableViewportSize(new Dimension(int, int));

• 将JPanel默认的 LayoutManager FlowLayout（在 API 中实现）更改为BorderLayout或GridLayout

Answer 2

您可以更改 JScroller 首选大小，因为表格通常放在滚动条内。

scrollerPhone.setPreferredSize(new Dimension(600, 400));
