如何在两列FPDF中分页

Question

我想使用FPDF将页面分成两列。我正在使用下面的代码，它在两个cloumn中创建了pdf，但问题是列之间的差距有点大。我想减少列之间的差距。

我的代码在这里

class PDF extends FPDF
{
protected $col = 0; // Current column
protected $y0;      // Ordinate of column start

function Header()
{
}

function Footer()
{
}

function SetCol($col)
{
    // Set position at a given column
    $this->col = $col;
    $x = 10+$col*50;
    $this->SetLeftMargin($x);
    $this->SetX($x);
}

function AcceptPageBreak()
{
    if($this->col<2)
    {
        // Go to next column
        $this->SetCol($this->col+2);
        // Set ordinate to top
        $this->SetY($this->y0);
        // Keep on page
        return false;
    }
    else
    {
        // Go back to first column
        $this->SetCol(0);
        // Page break
        return true;
    }
}

function ChapterBody($file)
{
    $txt = file_get_contents($file);
    $this->SetFont('Times','',12);
    $this->MultiCell(100, 7, $txt);

    $this->Ln();
    $this->SetCol(0);
}

function PrintChapter($num, $title, $file)
{
    // Add chapter
    $this->AddPage();
    $this->ChapterBody($file);
}
}

$pdf = new PDF();
$title = '20000 Leagues Under the Seas';
$pdf->SetTitle($title);
$pdf->SetAuthor('Jules Verne');
$pdf->PrintChapter(1,'A RUNAWAY REEF','20k_c1.txt');
$pdf->Output();

您正在跳至第三列。请参阅下面的每页两列：

function AcceptPageBreak()
{
    if($this->col<1)
    {
        // Go to next column
        $this->SetCol($this->col+1);
        // Set ordinate to top
        $this->SetY($this->y0);
        // Keep on page
        return false;
    }
    else
    {
        // Go back to first column
        $this->SetCol(0);
        // Page break
        return true;
    }
}
