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.
