hola, tengo el siguiente codigo para exportar a excel pero no se como autoajustar celdas:
Código Delphi

try

for I := 1 to strtoint ( Edit2.Text ) do for J := 1 to strtoint ( Edit1.Text ) do begin
case RadioGroup1.ItemIndex of
0: XlsWriteCellNumber(FStream, I, J, 34.34);
1: XlsWriteCellRk(FStream, I, J, 3434);
2: XlsWriteCellLabel(FStream, I, J, Format('Cell: %d,%d', [I, J]));
else ;
end;
end;
XlsEndStream(FStream);
finally
FStream.Free;
end;
ShellExecute(Handle,nil, PChar( aa ), '', '',SW_SHOWNORMAL) ;
end;
procedure TForm1.Button2Click(Sender: TObject);
begin
close ;
end;
end.
No se si alguno me podria ayudar para poder autoajustar las celdas.
Muchas Gracias
