Hi, I think, this is the easiest way, if you need such output:
In[..]:= Table[{"foo"[x], foo[x]}, {x, 1, 5}] // TableForm
Out[..]/TableForm:=
foo[1] 1
foo[2] 4
foo[3] 9
foo[4] 16
foo[5] 25
But be sure, that this is something like a trick, because "foo"[x] and foo[x]
are two different things...
In[..]:=FullForm[%]
Out[..]:=List[List["foo"[1], 1], List["foo"[2], 4], List["foo"[3], 9],
List["foo"[4], 16], List["foo"[5], 25]]
