Jtable, issues with displaying sorting icon TableHeader with custom renderer and system L&F

Question

I created a custom renderer to my JTabe header but after sorting the table, the sorting icon does not appear when I'm using the default system L&F (in my case windows 8) but the icon appears when I use the Java L&F.
With Java L&F:

With System L&F:

And this is my class renderer:

private class HeaderRenderer implements TableCellRenderer{
        private final LineBorder lb = new LineBorder(new Color(0, 152, 206));
        private final Dimension dim = new Dimension(150, 25);
        private TableCellRenderer delegate;

        public HeaderRenderer(TableCellRenderer delegate) {
            this.delegate = delegate;
        }

        @Override
        public Component getTableCellRendererComponent(JTable table,Object value, boolean isSelected, boolean hasFocused, int row, int column) {
            Component comp = delegate.getTableCellRendererComponent(table, value, isSelected, hasFocused, row, column);

            if (comp instanceof JLabel) {
                JLabel label = (JLabel) comp;
                label.setBackground(Color.WHITE);
                label.setPreferredSize(dim);
                label.setHorizontalAlignment(SwingConstants.CENTER);
                label.setBorder(lb);
            }

            return comp;
        }

    }

Use:

JTableHeader tableHeaderCompnoent = table.getTableHeader();
tableHeaderCompnoent.setDefaultRenderer(new HeaderRenderer(tableHeaderCompnoent.getDefaultRenderer()));

Answer 1

[...] the sorting icon does not appear when I'm using the default system L&F (in my case windows 8) but the icon appears when I use the Java L&F.

The difference between the default L&F (Metal) and the system L&F is that the first one draws the sorting icon in the center (vertical alignment) of the header cell and the latter draws it in top of the header cell.

What happens next is that you draw a border for the header cells. A border is painted from the edge of the component inwards, meaning it paints over the component's area. Since the sorting icon is on the edge for the system L&F, it is painted over by the border.

You can solve this by removing the border, or adding the label to a JPanel which will handle the border instead:

@Override
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocused, int row, int column) {

    Component comp = delegate.getTableCellRendererComponent(table, value, isSelected, hasFocused, row, column);
    JPanel panel = new JPanel(new BorderLayout());
    if (comp instanceof JLabel) {
        JLabel label = (JLabel) comp;
        label.setBackground(Color.WHITE);
        label.setHorizontalAlignment(SwingConstants.CENTER);
        panel.add(label);
        panel.setBorder(lb);
    }
    return panel;
}

I removed setPreferredSize as noted by @mKorbel and the dim field should be removed with it.

Also, in the lines

JTableHeader tableHeaderCompnoent = table_1.getTableHeader();
tableHeaderCompnoent.setDefaultRenderer(new HeaderRenderer(tableHeaderCompnoent.getDefaultRenderer()));
table_1.getTableHeader().setDefaultRenderer(new HeaderRenderer(tableHeaderCompnoent.getDefaultRenderer()));

the 2nd and 3rd are the same, you can remove the 3rd.
