Hello dn77,
Here's is a little sample I just rigged up, hope it helps.
import java.awt.*;
import javax.swing.*;
public class TestOne{
     public static void main(String arg[]) {
          Object rows[][] = {
               {"One", "1", "I"},
               {"Two", "2", "II"},
               {"Three", "3", "III"},
               {"Four", "4", "IV"},
               {"Five", "5", "V"},
               {"Six", "6", "VI"},
               {"Seven", "7", "VII"},
               {"Eight", "8", "VIII"},
               {"Nine", "9", "IX"},
               {"Ten", "10", "X"},
               {"Eleven", "11", "XI"},
               {"Twelve", "12", "XII"},
               {"Thirteen", "13", "XIII"},
               {"Fourteen", "14", "XIV"},
               {"Fifteen", "15", "XV"},
               {"Sixteen", "16", "XVI"},
               {"Seventeen", "17", "XVII"},
               {"Eighteen", "18", "XVIII"},
               {"Nineteen", "19", "XIX"},
               {"Twenty", "20", "XX"}
          String headers[] = {"Notation", "Decimal", "Roman"};
          JFrame frame = new JFrame("3 Column header");
          JTable table = new JTable(rows, headers);
          JScrollPane scrollPane = new JScrollPane(table);
          frame.getContentPane().add(scrollPane, BorderLayout.CENTER);
          frame.setSize(300,150);
          frame.setVisible(true);
