remove cell borders in jtable

I have my custom cell renderer and want to remove the border of the cell.
what should I do? I tried setBorder but it doesn't work.

Here is my renderer code:

public class MyTableCellRenderer extends DefaultTableCellRenderer {

    private static final long serialVersionUID = -1195682136616306875L;

    public Component getTableCellRendererComponent(JTable table, Object value,
            boolean isSelected, boolean hasFocus, int row, int column) {
        Component c = super.getTableCellRendererComponent(table, value,
                isSelected, hasFocus, row, column);
        if (!isSelected) {
            if (row % 2 == 0 && row != 1) {
                c.setBackground(new Color(255, 255, 150));
            } else {
                c.setBackground(Color.WHITE);
            }
        } else {
            c.setBackground(new Color(255, 230, 255));
        }
        c.setBorder(BorderFactory.createEmptyBorder(0, 0, 0, 0));
        return c;
    }
}
