General ⇒ Build a table with partial horizontal lines

[iperten]

Hi!

Is there anyone who can help me in building this table please?

Three columns and 12 rows.
The first column is made of a couple of \multirow command: 8 and 4 rows respectively.
The second and third columns must have rows divided by horizontal lines but NOT the first one (this is what I'm fighting against at most).

Thank you.

Guys, I've just found out the command \cline{}... it works with what I have to make.
Thank you in any case!
