let me explain more....

actually, my arrays like:

Array A (2 dimension)
A, 1, 2, 3, 4,
B, 5, 6, 7, 8
C, 9, 10, 11, 12,

Array B (2 dimension)
A, A1, A2, A3, A4,
C, C9, C10, C11, C12,
B, B5, B6, B7, B8

output:
A, 1, 2, 3, 4, A1, A2, A3, A4
B, 5, 6, 7, 8, B5, B6, B7,B8
C, 9, 10, 11, 12, C9, C10, C11, C12
