Regexp tip

Hello,

I'm just starting working on it. I'd like to get a tip
For istance if I have a file like:

Code:
a      b    c
d     e     f
....

and I wanna get:

Code:
1a   &    2b   &  3c
0d   &    8e    &   4f
.....

I would like to use sed and come up with a regular expression that works. I was trying:

Code:
s/\s?/\&/g

But I'm wrong. can anyone suggest the right please?

Thx
