title: JTable's scroll doesn't move to the bottom when rows added
body: <p>How to scroll to last row of JTable automatically? I searched google few times, but I couldn't find solution. </p>
  
  <pre><code>        jTable1.setModel(new javax.swing.table.DefaultTableModel(
              new Object [][] {
                  {"aaaaa", "bbbb", "cccc", "dddd"},
              },
              new String [] {
                  "Title 1", "Title 2", "Title 3", "Title 4"
              }
          ));
  
      jScrollPane1.setViewportView(jTable1);
      jTable1.scrollRectToVisible(jTable1.getCellRect(jTable1.getRowCount()-1, 0, false));
  </code></pre>
  
  <p>This avobe is part of my source. I'm adding the row in another class there is no problem to adding data. the scroll is fixed on the top of row. How can I able to solve this problem?  </p>
