title: Update particular cell in Handsontable
body: <p>Is it possible to force update only one td (cell) for view ?
  There is a method <code>hot.render()</code>, but it rerenders all cells.</p>
  
  <p>I want to update table content JSON data (<code>hot.getData()</code>) using ajax, but I can't find how to force render the table. My table is so huge to rerender each time I receive the data.</p>
  
  <p>E.g.,</p>
  
  <pre><code>$.ajax(url,... ,success: function(d){
  var data = hot.getData();
  data[parseInt(d['row'],10)][d['col']] = d['value'];
  hot.render();//please, change this function into more simple.
  },
  ...
  );
  </code></pre>
  
  <p>is it possible to update a TD-cell at <code>[row,col]</code>?</p>
