    <p>Never forget to call grid.startup(), since the column width
    calculation and layout rendering need to access the geometry
    information of grid DOM nodes.</p>

  <p>If I have the grid with columns, that have no width specified, and <code>autoWidth</code> is set to <code>false</code>, <code>startup()</code> calculates the size of columns so, that they fill the whole viewport horizontally. However, if viewport is expanded, and extra empty space is inserted after the last column. If the viewport is narrowed, the last columns are not more visible (and no scroll is rendered).</p>
  
  <p>So I think the best workaround is to launch the recalculation of columns sizes manually, after the viewport was resized. But I can't find an API method to do that.</p>
  
  <p>How to call column width recalculation and layout rendering on existing grid?</p>
