title: How to compare 2 dataTables
body: <p>I have 2 datatables and I just want to know if they are the same or not. By "the same", I mean do they have exactly the same number of rows with exactly the same data in each column, or not.  I'd love to write (find) a method which accepts both tables and returns a boolean.  </p>
  
  <p>How can I compare 2 datatables in this way?  Both have identical schemas.</p>
