FPDF ต้องการแสดงข้อมูล fetch array เป็น 2 column ใช้ while loop แล้วมันแสดงข้อมูลไม่ครบ

function viewTable($db){
        $this->AddFont("THSarabunNew","","THSarabunNew.php");
        $this->SetFont("THSarabunNew_B","",10);
        $stmt = $db->query('select * from employee where work = "หัวหน้าส่วน" or work = "สารบรรณ" or work = "ขนส่งทั่วไป" and position <> "ลูกจ้างเหมา"');
        $stmt2 = $db->query('select * from employee where work = "ขนส่งวัสดุครุภัณฑ์" or position = "ลูกจ้างเหมา" or work = "-"');
        while($data = $stmt->fetch(PDO::FETCH_OBJ) and $data2 = $stmt2->fetch(PDO::FETCH_OBJ)){
            
            $this->Cell(14,5.1,iconv('UTF-8', 'TIS-620', $data->number),1,0,C);
            $this->Cell(19,5.1,iconv('UTF-8', 'TIS-620', $data->first_name),LB,0,C);
            $this->Cell(19,5.1,iconv('UTF-8', 'TIS-620', $data->last_name),RB,0,C);
            $this->Cell(13,5.1,iconv('UTF-8', 'TIS-620', $data->position),1,0,C);
            $this->Cell(15,5.1,iconv('UTF-8', 'TIS-620', ''),1,0,C);
            $this->Cell(15,5.1,iconv('UTF-8', 'TIS-620', $data->job),1,0,C);

            $this->Cell(14,5.1,iconv('UTF-8', 'TIS-620', $data2->number),1,0,C);
            $this->Cell(19,5.1,iconv('UTF-8', 'TIS-620', $data2->first_name),LB,0,C);
            $this->Cell(19,5.1,iconv('UTF-8', 'TIS-620', $data2->last_name),RB,0,C);
