Hello.

Copy/Paste the following to a notebook, select the cell and press Shift
+Enter

Print["your function"]
f[x_, y_] = 2*x + 3*y
Print["your list of data"]
dat = Table[f[x, y], {x, 0, 3, 1}, {y, 0, 4, 2}]
Print["your desired output"]
dat // TableForm[#1, TableAlignments -> Center, TableSpacing -> {2,
2},
   TableHeadings -> {None, (StyleForm[#1, FontSize -> 14, FontColor ->
Red] & ) /@ {"x", "y", "f[x,y]"}}] &


The key here is TableForm and its Options.

?? TableForm
TableForm[list] prints with the elements of list arranged in an array
of \
rectangular cells.
Attributes[TableForm] = {Protected, ReadProtected}
Options[TableForm] := {TableAlignments -> Automatic, TableDepth ->
Infinity, TableDirections -> Column, TableHeadings -> None,
TableSpacing -> Automatic}

Execute the following command to get futher information about its
Options

Options[TableForm];
(Information[Evaluate[#1[[1]]]] & ) /@ %;

"TableAlignments is an option for TableForm and MatrixForm which
specifies how entries in each dimension should be aligned."
Attributes[TableAlignments] = {Protected}

"TableDepth is an option for TableForm and MatrixForm which specifies
the maximum number of levels to be printed in tabular or matrix
format."
Attributes[TableDepth] = {Protected}

"TableDirections is an option for TableForm and MatrixForm which
specifies whether successive dimensions should be arranged as rows or
columns."
Attributes[TableDirections] = {Protected}

"TableHeadings is an option for TableForm and MatrixForm which gives
the labels to be printed for entries in each dimension of a table or
matrix."
Attributes[TableHeadings] = {Protected}

"TableSpacing is an option for TableForm and MatrixForm which
specifies how many spaces should be left between each successive row
or column."
Attributes[TableSpacing] = {Protected}

Also

FrontEndExecute[{HelpBrowserLookup["MainBook", "TableForm"]}]

Note that searching to my archives you can see a post of mine asking
how is it possibly
to get a table similar to that it would appear in a book (i.e. draw
vertical and horizontal lines
between rows and columns!).
