How to merge two matrix and create a table

I've got two matrix

A 
1,24  0,915  1,67  0,34
1,45  0,784  1,14  0,30
1,31  0,834  1,12  0,36

B
1,06  0,82  1,38  0,41
1,35  0,72  1,09  0,39

I'd like to get

C
1,45   1,06    0,784   0,82  1,14  1,38  0,30  0,41
1,31   1,35    0,834   0,72  1,12  1,09  0,36  0,39

And then create a table. For the table the idea is that the columns must be named in groups of 2, (column1 and 2 same name, column 3 and 4 same name....). thank you very much!!!!

Can you explain in words how this array was created? Like will A and B ever have different sizes? Than your example? Does the first row of A always get ignored? Will B always have one less row than A?
