title: Specific element on top oflist CellTable/ Pager
body: <p>is it possible to have a specific element on top of the list?</p>
  
  <p>backgoround: 
  I have an event app, where new events are constantly added. The events are orderd by date. If an event passes, it is still on top of the page. Now that some time passed, the first elements are all over, so the first paged doesn't display any necassery data anymore. To get to events which will happen, the user has to click on the pager button.
  I want this events to be displayed on top, and if the user want's to see previous events, he has to click the back button of the pager.</p>
  
  <p>What have I tried:</p>
  
  <pre><code>cellTable.setVisibleRange(overElements, (overElements + totalEementCount));
  </code></pre>
  
  <p>this mixes up the whole pager logic, and the user can't switch from pager to page anymore.</p>
  
  <pre><code>SingleSelectionModel&lt;JSEvents&gt; selectionModel = new SingleSelectionModel&lt;JSEvents&gt;();
  ...
  selectionModel.setSelected(nextEvent, true);
  </code></pre>
  
  <p>this selects the right element, and moves the pager to it, but the other elements are still visible, so if I have a few "over" events and in the worst case, only have a single "comming" event in the table. Also it is the usability is bad, since the user has to look which event is next and doesn't have it on top of the page...</p>
