Thanks for destroying my day.
Here's a much longer alternative
' ' (,{~[:((+.|.)@= ({"0 1) 0&,.) 1+i.@#@]) 'baabb'
b b
a a
a
b b
b b
_ (,{~ [: ((+.|.)@=({"0 1) 0&,.) 1+i.@#@]) 1 2 1 2
1 _ _ 1
_ 2 2 _
_ 1 1 _
2 _ _ 2

The expression fails if the argument has duplicate items. e.g.
((+.|.)@={"0 1 ' '&,.)'aabbb'
|length error

That is lovely Arie,
It is that kind of elegance that I was chasing with my rougher attempts.
Using the (+.|.) hook simplifies (|.+.]) precisely and the {" 0 1
combined with ' '&,. means that the selection of the string becomes a
choice in each row of displaying either the corresponding element of the
string or a blank.
Cheers, bob
