title: Create MouseEvent for JTableHeader for a JTable with TableModel
body: <p>I want to have the following function: by clicking the header of a column, I can select the column and hide the other columns. At the same time, I want to show semantic zooming information for the selected column.</p>
  
  <p>Now I am just registering a mouse listener to selected header but getting the following exception:</p>
  
  <p>[relevant exception info]</p>
  
  <pre><code>Exception in thread "AWT-EventQueue-0" java.lang.IndexOutOfBoundsException: Index: 50, Size: 50

  <p>I am wondering why the clicking event in JTable will related to getValueAt() method in TableModel class. For all the examples of teaching adding mouse listener for header clicking, no one mentions this part as well. Could anyone help me figure out the problem? The register part code is as follows:</p>
  
  <pre><code>  public MyJTable() {
      super();
      this.addMouseListener(new MouseAdapter() {
         public void mouseClicked(MouseEvent e) {
             JTableHeader header = getTableHeader();
             if (header.equals(e.getSource())){
                  if (e.getClickCount()==2){
                     int index = convertColumnIndexToModel(columnAtPoint(e.getPoint()));
                     if (index &gt;= 0) {
                        System.out.println("Clicked on column " + index);
  
                      }
                  } 
              } else { //clicking event when clicking any cell of this Table
        }
      });
  </code></pre>
  
  <p>I had thought maybe because the header==null, there is no chance to get into the first if condition. However, after checking, header!=null and I had override getColumnName in myAbstractTableModel.So now I am running out of ideas...</p>
  
  <p>[New edit]</p>
  
  <p>Now I try to add listener for header, but the error is the same. I found that when I double click the header, the exception is the same as above, and also shows the selected header's information as I coded. I guess the exception is because the table's header has sorting listener. I tried to setAutoCreateRowSorter(false); and also summaryHeader.setReorderingAllowed(false); but it still doesn't work. The relevant new code is as follows:</p>
  
  <pre><code>  public JTableSummary() {
      super();
      setAutoCreateRowSorter(false);
      JTableHeader summaryHeader = this.getTableHeader();
      summaryHeader.setReorderingAllowed(false);
      summaryHeader.addMouseListener(new MouseAdapter(){
             @Override
          public void mouseClicked(MouseEvent e) {
              if (e.getClickCount()==2){
                     int index = convertColumnIndexToModel(columnAtPoint(e.getPoint()));
                     if (index &gt;= 0) {
                        System.out.println("Clicked on column " + index);
                      }
                  //} 
              }
      });
  </code></pre>
  
  <p>I suppose the current problem is how to effectively disable header sorting listener(I can see sorting icon - a triangle appeared upward/downward when I click the header) and to make my own listener workable?</p>
  
  <p>Thanks in advance for your help!</p>
