hi yehuda,
mathematica 5.1 under os x.
there's nothing syntactically (or otherwise) wrong with
Table[{HoldForm[foo[i]], foo[i]}, {i, 5}] // TableForm
but notice that it outputs
foo[i] 1
foo[i] 4
foo[i] 9
foo[i] 16
foo[i] 25
which is not nearly as interesting as printing out foo[1], foo[2],
foo[3], ..., in the left-hand column.
anyway, treating "foo[" and "]" as strings in your second solution
(and dr bob's solution) works perfectly.
trevor.
