Create a calculated table

Hi guys,

I've got a table like this one:

ID  COLUMN

1        22;25

2         10;5

3         100;70

from which I'd like to create this new one:

ID  COLUMN

1        22

1        25

2         10

2         5

3         100

3         70

What kind of DAX transformation could I apply?

Thanks in advance for any hint
