How can I right-align a table header?

Question

Does anyone know a way to right-align a table header?
For example, in the table below I want the word 'Price' to be right-aligned. I could set the table's 'header renderer' to be a right-aligned DefaultTableCellRenderer, but then the header would look like a cell, not a header. Why can't swing be simple, like table.getColumn(1).setAlignment(Column.RIGHT) ????
public class TestTableHeader {
     public static void main(String[] args) throws Exception {
          JFrame frame = new JFrame("Test");
          Object[][] rowData = new Object[][] { { "General Electric", "$100.60" },
                    { "IBM", "$5.20" }, { "Wal-mart", "$17.00" } };
          JTable table = new JTable(rowData, new Object[] { "Name", "Price" });
          DefaultTableCellRenderer renderer = new DefaultTableCellRenderer();
          renderer.setHorizontalAlignment(DefaultTableCellRenderer.RIGHT);
          table.getColumnModel().getColumn(1).setCellRenderer(renderer);
          frame.getContentPane().add(new JScrollPane(table));
          frame.setSize(400, 300);
          frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
          frame.setVisible(true);
}

I modified your code an came up with a solution to the problem.
import java.awt.Component;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableCellRenderer;
public class TestTableHeader {     
     public static void main(String[] args) throws Exception {
          JFrame frame = new JFrame("Test");
          Object[][] rowData = new Object[][] {
                    { "General Electric", "$100.60" }, { "IBM", "$5.20" },
                    { "Wal-mart", "$17.00" } };
          JTable table = new JTable(rowData, new Object[] { "Name", "Price" });
          RightAlignRender right = new TestTableHeader().new RightAlignRender();
          table.getColumnModel().getColumn(0).setHeaderRenderer(right);
          table.getColumnModel().getColumn(1).setHeaderRenderer(right);
          frame.getContentPane().add(new JScrollPane(table));
          frame.setSize(400, 300);
          frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
          frame.setVisible(true);
     public class RightAlignRender extends DefaultTableCellRenderer {
          public Component getTableCellRendererComponent(JTable table,
                    Object arg1, boolean arg2, boolean arg3, int arg4, int column) {
               Component toReturn = table.getTableHeader().getDefaultRenderer().getTableCellRendererComponent(table,
                         arg1, arg2, arg3, arg4, column);
               switch (column) {
               case 0:
                    ((JLabel) toReturn).setHorizontalAlignment(DefaultTableCellRenderer.CENTER);
                    break;
               case 1:
                    ((JLabel) toReturn).setHorizontalAlignment(DefaultTableCellRenderer.RIGHT);
                    break;
               return toReturn;
}
