打印pdf的代码如下:

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);

            $fill=!$fill;
        }
        $this->Cell(array_sum($w), 0, '', 'T');
    }

我想将标题添加到每一页的表格列中。截图附在这个问题上。在第一个屏幕截图中显示了标题，但在第二个屏幕截图中没有显示标题。如何在后续页面上显示这些列标题？请帮我解决这个问题。在此先感谢。这张图片是 pdf 表格的第一页。

最佳答案

另一种方法是在 html 中简单地使用 THEAD 标签。

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

似乎 TCPDF 在每一页上都重复了标题。

关于php - 如何在 tcpdf 的每一页上放置表格的列标题？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/14274224/
