jscrollbar

First, add your JTable inside a JScrollPane and set the policy for the existence of scrollbars: new JScrollPane(myTable, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED); Then, indicate that your JTable must not auto-resize the columns by setting the AUTO_RESIZE_OFF mode: myJTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
