[O] Could org-mode implement multiple rows in tables?

[Ma Jiehong]

Hello!

First of all, I am pleased to send my first email to the mailing list of 
org-mode! I have been using org-mode for several years, and I am very 
happy with it.

However, I would like to know if a new feature could be implemented.

Currently, org-mode tables are neat, and very easy to use. One of the 
features available, is column grouping by adding "<" and ">" to the 
required columns.

But what about  having some cells spanning through more than 1 row (that 
is to say, vertically)?

Was that already been considered in the past, and if so, why was it 
rejected? Perhaps, this could be feasible now?

Regards,
