merging tables/ deleting holes

P: n/a
hy everyone;
I have a problem that could be seen by 2 differents point of view
1)
I'm wondering if it is possible to "merge" 2 tables (TA, TB) in 3th
table (TC) in such a way:

TA TB TC
-------------- ------------- ----> -------------------------
field1 field2 field1 field2 ----> field1 field2 field3
-------------- ------------- ----> ------------------------
1 10A 1 20B 1 10A 20B
1 30B 1 30B

and NOT

TC
-----------------------------
field1 field2 field3
-----------------------------
1 10A 20B
1 10A 30B
2)
I wonder if it's possible to "compact"/"optimize" ( can't find other
therms) one table removing "holes"
TC
-----------------------------
field1 field2 field3
-----------------------------
1 10A <-- "HOle"
1 20B
1 30B

Thank's in advance if someone who have already faced this problem can
help me.
