title: insert data into specific column cell using datatables jquery
body: <p>I've searched into the documentation of data tables of how one can add data to the table here 
  <a href="https://datatables.net/examples/data_sources/index.html" rel="nofollow">https://datatables.net/examples/data_sources/index.html</a> but no where I could find a way to insert data into a single cell for a given column. For example, I need sth like:</p>
  
  <pre><code> "columns": [ {target (0), "value which will be inserted"} ]
  </code></pre>
  
  <p>There is a way to inser data from an array but each section of the array contains values for the whole row ( see here <a href="https://datatables.net/examples/data_sources/js_array.html" rel="nofollow">https://datatables.net/examples/data_sources/js_array.html</a>) but I need to insert data into different cells in respect with the columns since I don't know the column labels initially. This is because the data will be in json format and first I need to extract the unique dates for each json object. These will be my column headers. And then for each of the objects based on its date I need to put it into the relevant date column. So the logic should be sth like:</p>
  
  <pre><code> if this date column (from the table) == json object date then put it there
  </code></pre>
  
  <p>Thanks</p>
