title: Adding a DataTable to an existing DataTable cells
body: <p>Having this snippet:</p>
  
  <pre><code>DataTable dt;
  
  //...
  //Fills dt with data (hidden)
  //...
  
  dt.Columns.Add("newCol");
  DataTable dt2;
  
  //...
  //Fills dt2 with data (hidden)
  //...
  
  dt.Rows[0]["newCol"] = dt2;
  System.Diagnostics.WriteLine(dtRows[0]["newCol"]);
  </code></pre>
  
  <p>It prints me empty, so aparently I am not being able to add a datatable to an existing datatable cell.
  I have tried to print both datatable's contents, prior to the assign, and they correctly print out the data.</p>
  
  <p>What am I doing wrong?</p>
