title: How to update data in datatable column
body: <p>Can someone help me loop through all the rows in a datatable column and update the data in it? So far I've found a way to loop through a column:</p>
  
  <pre><code>var table = $("#my_table").DataTable();
  table.column(2)
      .data()
      .each(function(value, index) {
          console.log(value);
          value = 'abc123'; //this does not work
      });
  </code></pre>
  
  <p>However, I'm not sure how to update that value.. Can someone help?</p>
  
  <p>Thanks in advance! </p>
