title: about column's width of a JTable in a JScrollPane
body: <p>i want to set each column of a JTable in a JScrollPane with a fixed num width, but i cannot do it with <code>infoTable.getColumnModel().getColumn(0).setPreferredWidth(10);</code>
  i use the default layout of JScrollPane and add the table with the scrollPane's setViewPortView(infoTable) in j2se 1.4. 
  How can i get this done?
  here is my code</p>
  
  <pre><code>private javax.swing.JButton jButton1;
  private javax.swing.JScrollPane jScrollPane1;
  public TableFrame() {
  
      jScrollPane1 = new javax.swing.JScrollPane();
      jButton1 = new javax.swing.JButton();
  
      setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
  
      jScrollPane1.setBorder(javax.swing.BorderFactory.createLineBorder(
          new java.awt.Color(0, 0, 0)));
  
      jButton1.setText("jButton1");
      jButton1.addActionListener(new java.awt.event.ActionListener() {
          public void actionPerformed(java.awt.event.ActionEvent evt) {
              jButton1ActionPerformed(evt);
          }
      });
  
      this.setSize(new Dimension(600, 600));
      this.jScrollPane1.setSize(500, 500);
      this.getContentPane().add(this.jScrollPane1, BorderLayout.CENTER);
      this.getContentPane().add(this.jButton1, BorderLayout.WEST);
      table = new JTable(new javax.swing.table.DefaultTableModel(100, 2));
      this.jScrollPane1.setViewportView(table);
      table.getColumnModel().getColumn(0).setWidth(10);
  }
  </code></pre>
  
  <p>ps. Thx for replying I need the column can be dragged to resize, so i cannot set the max and min size</p>
