The Data Table on v8.06 and v8.07 seems behave differently. Below image shows a TeeChart of the same program. Upper one is TeeChart v8.06 on D2007. Lower one is v8.07 on D2007.
After upgraded to v8.07, Data Table with more number of columns seems okay, but if number of columns is smaller, like 3, the Data Table grid falled out of the TChart boundary. Some charts even worse.
See attached project and images.
My temporary solution is add these two statement everytime I change or enlarge the chart:
Chart1.BottomAxis.MinimumOffset := 0;
Chart1.BottomAxis.MaximumOffset := 0;
So, the problem was not related to the Data Table. v8.07 will alter the above two properties automatically. Sometimes even I set it in the Edtior during design-time, these two properteis will automatically changed to whatever it wants.
Most likely related to the fix for TV52014436 in TeEngine.pas

Here is the simpler code to reproduce the difference between 8.06 and 8.07:
uses series;
procedure TForm1.FormCreate(Sender: TObject);
var i, j: integer;
begin
  for i:=0 to 2 do
  begin
    with Chart1.AddSeries(TBarSeries.Create(self)) as TBarSeries do
    begin
      MultiBar:=mbStacked;
      Marks.Visible:=false;
      for j:=0 to 2 do
        Add(Random(100), '1');
    end;
  end;
  with Chart1 do
  begin
    BottomAxis.MaximumOffset:=50;
    BottomAxis.MinimumOffset:=50;
  end;
  Chart1.Width := 896;
  Chart1.Height := 560;
end; [created:2010-04-19T11:03:32.000+01:00 reported by:narcis@steema.com reported in version:8.07.70413 (TeeChart VCL)]
