I have had similar issue long time ago. What I did is that I created two ListViews, one showing only the header on top of the other that has hidden header (see the attached pic).
In the Columns Editor I set the Minwidth, Maxwidth, and the Width of the columns of the Header ListView to be equivalent to the width of the second ListView columns to prevent the header columns of being re-sized so not to lose the columns' structure.

But if re-sizing the columns is necessary all you have to do is capturing the column resizing event at the Header ListView then re-size the other one to keep the respective columns in the same width.

To capture a column re-size event:

btw. I see now that I forgot to include the required uses clause... I think the example I provided requires CommCtrl, ComCtrls apart from the usual standard units. (can't try it right now)

I am trying HYPO's solution now, and i get a few errors:

  [Pascal Error] Main.pas(89): E2003 Undeclared identifier: '_HD_LAYOUT'
  [Pascal Error] Main.pas(94): E2003 Undeclared identifier: 'ListView_GetHeader'
  [Pascal Error] Main.pas(98): E2010 Incompatible types: 'TRect' and 'Pointer'
  [Pascal Error] Main.pas(101): E2003 Undeclared identifier: 'Header_Layout'

Is there something that I should declare at uses?

How can I call for this procedure and I want to change the height of the panels to 19.
Where in the code should I put 19.

Commented:
Yep, with Delphi 6, all I have to add is the CommCtrl unit to the uses clause... try that and it should work.

I made a small example in a button... just setup a list view on your form, then add a button, and try it out...

procedure TForm1.Button1Click(Sender: TObject);
begin
  SetListViewHeaderHeight(ListView1, 19 {HERE IS WHERE YOU PUT YOUR HEIGHT});
end;

I think you should be able to use it in one of the resize events... But I'll have to check if there are any issues with putting it there first...
