title: how to force sort on a JTable
body: <p>I already have this:</p>
  
  <pre><code>TableRowSorter&lt;FileTableModel&gt; rs = new TableRowSorter&lt;FileTableModel&gt;(ftm);
      rs.setComparator(COL_NAME, new Comparator&lt;DisplayFile&gt;() {
              //&lt;sorting code&gt;
          }
      });
      setRowSorter(rs);
  </code></pre>
  
  <p>and it works. It sorts the rows as it should when the user clicks on the header.
  I just can't figure out an easy way to sort the rows without the click on the header.
  I want rows to already be sorted when they are displayed (user can then change asc/desc/etc. by clicking on column headers.)</p>
  
  <p>How can i force the sorting? I know I could sort the rows in my TableModel, but i already have a working comparator, why not use it?</p>
