Re: table_attach_columns

Mary,

There is no problem in naming the dimensions. I only ask it because the
documentation says one thing and the function works in another way. And,
being this an error in the documentation, as we saw, I'd suggest to correct
it.

Thank you for all your help.

Best regards

Mateus
