How to get rid of the border with a JTable / JScrollPane

Question

If you run the small sample below you\'ll see a border around the center region. I\'m not sure why this border is showing.

It happens when a JTable is in a JScrollPane.

Answer 1

Interestingly the border disappears when you remove this line:

sp.setBorder(null);

Answer 2

I was looking for the answer for the same question but above answers could not do... so I found a better answer:

JScrollPane jsp = new JScrollPane();

//ur other codes

jsp.setViewportBorder(null);

Answer 3

To remove the border from all parts of the JScrollPane including the vertical and horizontal bar the following code works

JScrollPane jsp = new JScrollPane();
jsp.getVerticalScrollBar().setBorder(null);
jsp.getHorizontalScrollBar().setBorder(null);
jsp.setBorder(null);

Answer 4

I think the proper fix is to set the border on the viewportView to 'null'.

Answer 5

Use BorderFactory.createEmptyBorder() instead of null...

by using:

sp.setBorder(createEmptyBorder());

it works.

Your main method becomes:

public static void main(String[] args) {
    JFrame frame = new TestScrollPane();
    JPanel panel = new JPanel();
    JTable table = new JTable();

    panel.setLayout(new BorderLayout());
    panel.add(new JLabel("NORTH"), BorderLayout.NORTH);
    panel.add(new JLabel("SOUTH"), BorderLayout.SOUTH);

    JScrollPane sp = new JScrollPane(table);
    sp.setBorder(BorderFactory.createEmptyBorder());
    panel.add(sp, BorderLayout.CENTER);
    frame.add(panel);

    frame.setVisible(true);
}

Answer 6

For JTable table.setIntercellSpacing(new Dimension(0, 0)) works.
