Jtable columns not horizontally scrollable in NetBeans GUI builder?

Question

I have the following JTable in my program which is placed inside a JScrollPane. I made it using the GUI builder provided by Netbeans.

The problem is some of the columns in the table is not visible and there is no horizontal scroll bar. I even set the horizontalScrollBarPolicy to ALWAYS and it didnt help. So how do I make the table scrollable?

Answer 1

As @Andrew Thompson mentiond you should provide some code that addresses the problem. Without seeing your code it's hard to find out what's the problem. But a common workaround about that is as the following:

If you have correctly added your JTable to the ViewPort of a JScrollPane like this:

JTable jtable = new JTable();
//...
JScrollPane sc = new JScrollPane(jtable);
//sc.setViewportView(jtable); <- This way is correct too
//
getContentPane().add(sc);

Then the most probable problem is about the AutoResizeMode of your JTable . Try this:

jtable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

Hope this would help you.
