I have a list of values. There are three columns and almost hundred rows. The columns are labeled simply 3, 5, and 7. There are random values on the first column; for simplicity, I used a,b,c,d... Also, there are prices within the table. It looks similar to this:

1 2 3

a 10 20 30

b 40 50 60

c 70 80 90

d 100 110 120

e 130 140 150

f 160 170 180

g 190 200 210

My problem is that I need to allign all these values in two columns. The first column would read a1, a2, a3, b1, b2, b3, c1,c2,c3... and the second column would read the respective value, i.e., 10, 20,30, etc. So, what I need looks like this:

a1 10

a2 20

a3 30

b1 40

b2 50

b3 60

c1 70

c2 80

c3 90

d1 100

d2 110

d3 120

e1 130

e2 140

e3 150

f1 160

f2 170

f3 180

g1 190

g2 200

g3 210

Can anybody help me?

Thank you for your help.
