<Because of the lack of response to my previous 2

Not quite. With a little help of the Kernel it is possible,
even for the notebook Mathematica front end:
PrintNodeCoordinates[xyzcoor_] :=
Module[{numnod = Length[xyzcoor], t, n, c, tt, mx, nt},
t = Table[" ", {numnod + 1}, {4}];
For[n = 1, n <= numnod, n++, c = xyzcoor[[n]];
If[Length[c] <= 2, AppendTo[c, 0]];
If[Length[c] == 1, AppendTo[c, 0]];
t[[n + 1, 1]] = ToString[n];
t[[n + 1, 2]] = c[[1]];
t[[n + 1, 3]] = c[[2]];
t[[n + 1, 4]] = c[[3]]];;
t[[1]] = {"node", "x", "y", "z"};
tt = Map[ToString, t, {2}];
mx = Max[Map[StringLength, tt, {2}]];
nt = Map[(StringJoin @@ PadLeft[{#}, mx - StringLength[#], " "]) &,
tt, {2}];
Print @ StringDrop[ExportString[nt, "Table"], -1]
]; PrintNodeCoordinates[{{2, 3, 2000}, {5, a + b, 168.09}, {x_dir, y_dir,
z_dir}}]
This gives (unformatted) Cell[BoxData["\<\" node .... \"\>"], "Print"], which
is quite plain text.
BTW: does anybody know if there exists a ConversionOptions setting
for ExportString to not get the "\n" at the end of ExportString? Right now
ExportString[{"a"},"Table"] returns "a\n" .
This may be fine in some situations, but not for the case above (this is why I
added the StringDrop[ ,-1]
There should be more ConversionOptions documentation really.
E.g., does Export[ { { ... }, ... {} }, "Table" ]also take ConversionOptions
similar to TableForm? I don't know ... (anybody?, PJ?)
Maybe one could also get this type of formatting with J/Link and the
apropriate Java (JTable?) classes, but I found this too complicated.
