You could use my progr-align.el package:
www.xsteve.at/prg/emacs/progr-align.el
You specify a header line that matches the columns and the needed widths:
// #palign "\w" 4, "(\"\w+\"" 9, "\"" 19, "[0-9]+" 17, "[0-9]+"
Then you can put the cursor on a line or mark a region and call
M-x progr-align. That aligns the above code the way you wanted it.
Let me explain the #palign line:
"\w" matches foo, the column should be 4 characters wide
"(\"\w+\"" matches "arg1", columnwidth: 9 characters
"\"" matches "xxx", columnwidth: 19
"[0-9]+" matches 1, columnwidth: 17
"[0-9]+" matches 2, last column, no width needed
Stefan.

Look for pretty-column.el. It will do what you want and is easy to
use. I think I got it from gnu.emacs.sources, so chances are you can
find it in the Google group collection of postings.

I think that this package will work for you out of the box. I can't
remember where I found it.
