How to put column headings of a table on each page in tcpdf?

Question

The code used to print the pdf is as follows:

class MYPDF extends TCPDF {

    // Load table data from file
    public function LoadData($file) {
        // Read file lines
        $lines = file($file);
        $data = array();
        foreach($lines as $line) {
            $data[] = explode(';', chop($line));
        }
        return $data;
    }

    // Colored table
    public function ColoredTable($header,$data) {
        // Colors, line width and bold font
        $this->SetFillColor(233, 136, 64);
        $this->SetTextColor(255);
        $this->SetDrawColor(128, 0, 0);
        $this->SetLineWidth(0.3);
        $this->SetFont('', 'B');
        // Header
        $w = array(10, 40, 20, 20, 20, 20, 20);
        $num_headers = count($header);
        for($i = 0; $i < $num_headers; ++$i) {
            $this->Cell($w[$i], 7, $header[$i], 1, 0, 'C', 1);
        }
        $this->Ln();
        // Color and font restoration
        $this->SetFillColor(224, 235, 255);
        $this->SetTextColor(0);
        $this->SetFont('');
        // Data
        $fill = 0;
        foreach($data as $row) {
            $this->Cell($w[0], 6, $row[0], 'LR', 0, 'C', $fill);
            $this->Cell($w[1], 6, $row[1], 'LR', 0, 'L', $fill);
            $this->Cell($w[2], 6, $row[2], 'LR', 0, 'C', $fill);
            $this->Cell($w[3], 6, $row[3], 'LR', 0, 'C', $fill);
            $this->Cell($w[4], 6, $row[4], 'LR', 0, 'C', $fill);
            $this->Cell($w[5], 6, $row[5], 'LR', 0, 'C', $fill);
            $this->Cell($w[6], 6, $row[6], 'LR', 0, 'C', $fill);
            $this->Ln();
            $fill=!$fill;
        }
        $this->Cell(array_sum($w), 0, '', 'T');
    }
}

// create new PDF document
$pdf = new MYPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

// set document information
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('Nicola Asuni');
$pdf->SetTitle('TCPDF Example 011');
$pdf->SetSubject('TCPDF Tutorial');
$pdf->SetKeywords('TCPDF, PDF, example, test, guide');

// set default header data
$pdf->SetHeaderData(PDF_GYANKUTIR_LOGO, PDF_HEADER_LOGO_WIDTH, 'GyanKutir', 
'Jhunjhunu International Wisdom City
Near Khemi Shakti Temple
Jhunjhunu (Rajasthan)-333001');

// set header and footer fonts
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));

// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);

//set margins
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);

//set auto page breaks

//set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);

//set some language-dependent strings
$pdf->setLanguageArray($l);

// ---------------------------------------------------------

// set font
$pdf->SetFont('helvetica', '', 6);

// add a page
$pdf->AddPage();

//Column titles
$header = array('Rank', 'Student', 'Time Used', 'Correct Answers', 'Wrong Answers','Questions Skipped','Final Score');


$final_data = $smarty->fetch($file_to_show);

$file = fopen("text.txt","w+");

    file_put_contents($file,"");
    fwrite($file,$final_data);
    fclose($file);

ob_start();
        ob_flush();
//Data loading
$data = $pdf->LoadData('text.txt');

// print colored table
$pdf->ColoredTable($header, $data);

I want to add the headings to the table columns on each page. The screenshot is attached with this question. In the first screenshot the headings are getting displayed but in second screen shot the are not getting displayed. How to display those column headings on subsequent pages? Please help me out to resolve this issue. thanks in Advance.This image is the first page of a table in pdf.

Answer 1

Another method would be to simply use THEAD tag in html.

<table>
<thead>
    <tr><th>Heading</th></tr>
</thead>
<tbody>
    <tr><td>Many rows...</td></tr>
    <tr><td>of data</td></tr>
</tbody>
</table>

It appears TCPDF repeats the heading on every page.
