      There appears to be a problem when working with html tables in JEditorPane. If
      you try to open up a wide table (greater than the length of the frame) at times
      you lose the last few characters in the last cell. Here is some code for
      viewing the html page:
      ==========================

      import java.io.*;
      import java.util.*;
      import java.awt.*;
      import java.awt.event.*;
      import javax.swing.*;

      public class SessionDocument implements ActionListener
      {
         private JFrame frame;
         private JEditorPane editorPane;
         private String inputHTMLFilename;
         private int viewWidth;
         private int viewHeight;

         public SessionDocument(String inHTMLFilename)
         {
            frame = new JFrame();
            inputHTMLFilename = inHTMLFilename;
            viewWidth = 600;
            viewHeight = 500;
         }

         public void actionPerformed(ActionEvent e)
         {
            String cmd = e.getActionCommand();
            if (cmd.equals("Close"))
            {
            System.exit(0);
            }

         }

         public void displayFile()
         {
            try {
               String fHeader = new String("file:");
               String sTotal = "";
               sTotal = fHeader.concat(inputHTMLFilename);

               editorPane = new JEditorPane();
               editorPane.setEditable(false);
               editorPane.setContentType("text/html");
               // the next line fixes the error
               //editorPane.setMargin(new Insets(5,5,5,25));
               editorPane.setPage(sTotal);

               JScrollPane editorScrollPane = new JScrollPane(editorPane);
               editorScrollPane.setVerticalScrollBarPolicy
      (JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
               editorScrollPane.setPreferredSize(new Dimension(250, 145));

               frame.getContentPane().add(editorScrollPane, BorderLayout.CENTER);
               frame.setSize(viewWidth, viewHeight);

               JMenuBar menuBar = new JMenuBar();
               JMenu menu = new JMenu("Menu");
               menuBar.add(menu);
               JMenuItem close = new JMenuItem("Close");
               close.addActionListener(this);
               menu.add(close);
               frame.setJMenuBar(menuBar);
               frame.setVisible(true);
               frame.setTitle("Report Viewer");
            }
            catch (IOException e) {
               System.out.println("Error Displaying File!");
            }
         }

         public static void main(String[] args)
         {
            SessionDocument sDocument = new SessionDocument(args[0]);
            sDocument.displayFile();
         }
      }

      ============================
      When the frame opens scroll over to the far right. You should see that the
      last 0 is cut off. If you make the frame quite wide you'll see the correct
      value. You might have to resize the frame a couple of times to get the
      incorrect view. Now, if I add the currently commented out line to set the
      margins and change the right margin to 25 I can see all of the text. So my
      guess is that the scrollbar is taking up "space" on the editorPane and not
      being accounted for.

      Through examination I found another oddity. If you changed all of the "i"s in
      the column headers that consist of "Xixi..." to all "x"s you will find that the
      last 0 is not lost. Could this be due to handling font sizes differently?

      One other note. When running the exact same code in jdk1.2.2 everything works
      fine.

      Thanks
