No Way to add several columns at ones

[OriM17]

There is no way at least that I could find to add columns like rows
with rows I can do rows=(number of rows) but with columns there is no way to do that
If I am wrong please correct me and tell me how to do such thing
Thanks!

Not from the right click menu. It can be done programmatically using the autoAddColumns method.
