I'd like to avoid the performance cost of copying large amounts of data inside of tables. For example, if I wanted to add or remove columns from the table via a function, how would you do that without it creating a copy? Do you need to use handle classes or can this be acheived with the built-in tables?

I think adding and removing columns from tables is largely like adding/removing elements from cell vectors, i.e., it involves no data copying.

Thanks for providing that test! I see it's not making a copy.
