Var
   aCol : TListviewColumn;

begin
   aCol:=Listview1.Columns.Add;
   aCol.Caption:='Country';
   aCol:=Listview1.Columns.Add;
   aCol.Caption:='Region';
end;

It is possible to sort:

   Listview1.SortColumn:=0; // change to column you need
   Listview1.SortDirection:=sdAscending;
   Listview1.Sort;
