Document Library column header copy

Question

For a Document Library I would like to copy all the column headers including the managed metadata column headers and past them in another site's Document Library.

Answer 1

As you only want to hold the header, you can save this library as a library template including the content (Library settings > Save document library as template ).Download the template in the list template gallery.

Upload this library template to the site collection Site settings > Web Designer Galleries > List templates, then create a new library based on it.
