Problema con tabla en fpdf

[jandrogdz]

Buenas foro

Tengo un problema al tratar de crear una tabla con la librería FPDF.

Pero al tratar de hacer la tabla me arroja el ciclo pero en errores.
así esta el archivo para hacer la tabla:

Código PHP:

<?php
require('fpdf.php');
 
class PDF_MC_Table extends FPDF
{
var $widths;
var $aligns;
 
function SetWidths($w)
{
    //Set the array of column widths
    $this->widths=$w;
}
 
function SetAligns($a)
{
    //Set the array of column alignments
    $this->aligns=$a;
}
 
function Row($data)
{
    //Calculate the height of the row
    $nb=0;
    for($i=0;$i<count($data);$i++)
        $nb=max($nb,$this->NbLines($this->widths[$i],$data[$i]));
    $h=5*$nb;
    //Issue a page break first if needed
    $this->CheckPageBreak($h);
    //Draw the cells of the row
    for($i=0;$i<count($data);$i++)
    {
        $w=$this->widths[$i];
        $a=isset($this->aligns[$i]) ? $this->aligns[$i] : 'L';
        //Save the current position
        $x=$this->GetX();
        $y=$this->GetY();
        //Draw the border
        $this->Rect($x,$y,$w,$h);
        //Print the text
        $this->MultiCell($w,5,$data[$i],0,$a);
        //Put the position to the right of the cell
        $this->SetXY($x+$w,$y);
    }
    //Go to the next line
    $this->Ln($h);
}
 
function CheckPageBreak($h)
{
    //If the height h would cause an overflow, add a new page immediately
    if($this->GetY()+$h>$this->PageBreakTrigger)
        $this->AddPage($this->CurOrientation);
}
 
function NbLines($w,$txt)
{
    //Computes the number of lines a MultiCell of width w will take
    $cw=&$this->CurrentFont['cw'];
    if($w==0)
        $w=$this->w-$this->rMargin-$this->x;
    $wmax=($w-2*$this->cMargin)*1000/$this->FontSize;
    $s=str_replace("\r",'',$txt);
    $nb=strlen($s);
    if($nb>0 and $s[$nb-1]=="\n")
        $nb--;
    $sep=-1;
    $i=0;
    $j=0;
    $l=0;
    $nl=1;
    while($i<$nb)
    {
        $c=$s[$i];
        if($c=="\n")
        {
            $i++;
            $sep=-1;
            $j=$i;
            $l=0;
            $nl++;
            continue;
        }
        if($c==' ')
            $sep=$i;
        $l+=$cw[$c];
        if($l>$wmax)
        {
            if($sep==-1)
            {
                if($i==$j)
                    $i++;
            }
            else
                $i=$sep+1;
            $sep=-1;
            $j=$i;
            $l=0;
            $nl++;
        }
        else
            $i++;
    }
    return $nl;
}
}
?>
 

Y este es el que hace el pdf:

Código PHP:

header ('Content-type: text/html; charset=utf-8');
ob_end_clean();
require('../../libs/fpdf/PDF_MC_Table.php'); // tiene el require de fpdf.
 
class PDF extends FPDF
{
    //Encabezado de pagina
    function Header()
    {   
        $this->Image('../../imagenes/banner_pedidos.jpg',5,5,285,35,'JPG');
        $this->Cell(200,35,"","",1,'C');
    } 
    
    function Footer()
    {
        $this->SetFont('Arial','B',10);
        $this->SetY(-20);
        $this->SetFont('Arial','I',12);
        $this->Cell(0,10,'Pagina '.$this->PageNo().'/{nb}',0,1,'C');
    }
}
 
$pdf=new PDF('L','mm','A4');
    $pdf->AliasNbPages();
    $pdf->AddPage();    
    $pdf->Ln(5);
 
$pdf->Ln(5);
    $pdf->SetFont('Arial','',12);
    $pdf->SetTextColor(115,115,115);
    $pdf->SetFillColor(237,237,237);
    $pdf->SetDrawColor(215,215,215);
    $pdf->SetLineWidth(.1);
    $pdf->Cell(20,7,'Cantidad',"BRLT",0,'C',true);
    $pdf->Cell(117,7,'  Producto | Servicio',"BRLT",0,'L',true);
    $pdf->Cell(5,7,'P',"BRLT",0,'C',true);
    $pdf->Cell(5,7,"D","BRLT",0,'C',true);
    $pdf->Cell(5,7,"I","BRLT",0,'C',true);
    $pdf->Cell(30,7,"$ Precio U.","BRLT",0,'C',true);
    $pdf->Cell(30,7,"$ Importe","BRLT",0,'C',true);
    $pdf->Cell(63,7,"Observaciones","BRLT",1,'C',true);
    $pdf->Ln(1);
    
    $pdf->SetFont('Arial','',11);
    $dgral = $ped->productosDetalle($_GET['dt']);
    $contador = 0;
    
    $mc_table = new PDF_MC_Table();
    $mc_table->SetWidths(array(20,117,5,5,5,30,30,63));
    for($i=0;$i<1;$i++):
        $mc_table->Row(array("Cantidad","Descripcion","P","D","I","Precio","Importe","Observaciones"));
    endfor;
 

Esto me regresa:

Alguien me puede apoyar.
