You might be able to embed an excel spreadsheet into your app if you use the OLEContainer component and user it just like excel.
Someone else might be able to give you code on how to do this or supply another alternative.

Thanks. But it must be without Excel.

You may also use TStringGrid ('Additional' tab) and draw contents of cells in onDrawCell event (this is really simple).
Here's a small example:

object StringGrid1: TStringGrid
  Left = 8
  Top = 24
  Width = 561
  Height = 369
  DefaultDrawing = False
  GridLineWidth = 0
  Options = [goEditing]
  TabOrder = 0
  OnDrawCell = StringGrid1DrawCell
end

procedure TForm1.StringGrid1DrawCell(Sender: TObject; ACol, ARow: Integer; Rect: TRect; State: TGridDrawState);
var
  s : string;
begin
with StringGrid1, Canvas do begin
  s := Cells[aCol, aRow];
  Pen.Width := 1;
  if gdSelected in State then Pen.Color := $000000 else
  if gdFixed    in State then Pen.Color := $888888 else
  Pen.Color := $dddddd;
  if gdSelected in State then Brush.Color := $eeeeee else
  if gdFixed    in State then Brush.Color := $dddddd else
  Brush.Color := $ffffff;
  Rectangle(rect);
  Brush.Style := bsClear;
  with rect do
  if (length(s) > 0) and (s[1] = '=') then begin
    TextOut(left + (right - left - TextWidth('formula')) div 2, top + (bottom - top - TextHeight('formula')) div 2, 'formula');
  end else begin
    TextOut(left + (right - left - TextWidth(s)) div 2, top + (bottom - top - TextHeight(s)) div 2, s);
  end;
end;
end;

Notice that I've changed three settings for StringGrid1 to make it more "custom":
  DefaultDrawing = False
  GridLineWidth = 0
  Options = [goEditing] (removed )
