You do not have a key that sufficently indicates records to be joined, therefore this is not possible.
It seems you do not have primary key column in two tables. Whatever way you do the output would need to verified throughly.
If you are very sure that records that need to be joined are in same order in both the tables then in that case create new numeric column NEW_COLUMN in both the table and store record number that may be _N_ or something else whatever you like. This new column would act as suggorate key and now you can join two table with NEW_COLUMN and dept1.
