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]]
