How to adjust Multicell in Array FPDF

Question

i need a help on how to make the data inside the array to be in one ligne and same height in multicell

this is the result

and this is the code :

  $colored = false;
  foreach($products_info as $row){

      if($colored){
          $this->SetFillColor(218,218,218);              
      }else{
          $this->SetFillColor(255,255,255);
         
      }
    
    $this->Cell(40,15,ucwords($row["libelle"]),1,0,'L',$colored);
    
    $this->MultiCell(40,15,ucwords($row["description"]),1,1,'L',$colored);

    $this->Cell(40,15,number_format($row["prix_unitaire"],3,","," "),1,0,"C",$colored);
    $this->Cell(20,15,number_format($row["quantity"],3,","," "),1,0,"C",$colored);
    $this->Cell(10,15,number_format($row["largeur"],3,","," "),1,0,"C",$colored);
    $this->Cell(10,15,number_format($row["hauteur"],3,","," "),1,0,"C",$colored);
    $this->Cell(30,15,number_format($row["total_ht"],3,","," "),1,1,"R",$colored);
    $colored = !$colored;
  }

this is the old version before i add multicell

and this is the code :

      $colored = false;
  foreach($products_info as $row){

      if($colored){
          $this->SetFillColor(218,218,218);              
      }else{
          $this->SetFillColor(255,255,255);
         
      }
    
    $this->Cell(40,15,ucwords($row["libelle"]),1,0,'L',$colored);
    $this->Cell(40,15,ucwords($row["description"]),1,0,'L',$colored);
    $this->Cell(40,15,number_format($row["prix_unitaire"],3,","," "),1,0,"C",$colored);
    $this->Cell(20,15,number_format($row["quantity"],3,","," "),1,0,"C",$colored);
    $this->Cell(10,15,number_format($row["largeur"],3,","," "),1,0,"C",$colored);
    $this->Cell(10,15,number_format($row["hauteur"],3,","," "),1,0,"C",$colored);
    $this->Cell(30,15,number_format($row["total_ht"],3,","," "),1,1,"R",$colored);
    $colored = !$colored;
  }
