joining the tables using newly assigned keys

[Qlikuser09]

I have two sample tables like below

Table 1:

company code	Fields	Key1
AA	Management total	1
AA	staff total	2
AB	Management total	1
AB	staff total	2

Table 2:

Company code	Attributed fields	key 2
AA	Manager	1
AA	CIO	1
AA	IT Staff	2
AA	Dev Staff	2
AB	Manager	1
AB	CIO	1
AB	IT Staff	2
AB	Dev Staff	2

these tables are already joined by the primary Key company code, now I want to associate them based on Key 1 and Key 2
