That would require

  1a. Creating a native object.
  2a. Copying the table (body) data to that object.
  3a. Reversing the order of the data in the object.
  3b. nothing
  4a. Copying the data from the object to the DOM object.
  4b. Copying the data from the object to the DOM object
      in reverse order.

By contrast, you could just

  1c. Reverse the order of the nodes in the document tree in place.

Why is the former wiser?
