title: Copy DataTable from one DataSet to another
body: <p>I'm trying to add to a new DataSet X a DataTable that is inside of a different DataSet Y.
  If I add it directly, I get the following error:</p>
  
  <blockquote>
    <p><em>DataTable already belongs to another DataSet.</em></p>
  </blockquote>
  
  <p>Do I have to clone the DataTable and import all the rows to it and then add the new DataTable to the new DataSet? Is there a better/easy way to do it?</p>
