DomPDF 的 get_cellmap() 问题

问题描述 投票：0回答：7

我正在使用 DomPdf 并尝试将我的文件转换为 pdf，但遇到下面给出的奇怪错误

我用谷歌搜索了很多次并阅读了不同的论坛，但没有得到这个错误的原因。

请大家帮助我。

致命错误：未捕获错误：调用成员函数 get_cellmap() 在空值上 C:\xampp\htdocs\dom\dompdf\src\FrameReflower\TableCell.php:37 堆栈 跟踪：#0 C：\ xampp \ htdocs \ dom \ dompdf \ src \ FrameDecorator \ AbstractFrameDecorator.php（893）： Dompdf\FrameReflower\TableCell->回流(NULL) #1 C:\xampp\htdocs\dom\dompdf\src\FrameReflower\TableRow.php(52): Dompdf\FrameDecorator\AbstractFrameDecorator->reflow() #2 C：\ xampp \ htdocs \ dom \ dompdf \ src \ FrameDecorator \ AbstractFrameDecorator.php（893）： Dompdf\FrameReflower\TableRow->回流(NULL) #3

代码

require_once './dompdf/autoload.inc.php';
use Dompdf\Dompdf;

$dompdf = new Dompdf();
$dompdf->loadHtml(file_get_contents('./my-file.php'));

$dompdf->setPaper('A4','landscape');
$dompdf->render();

$dompdf->stream('codexworld',array('Attachment'=>0));

DomPDF 与 CSS 属性发生冲突，例如 

display
我不知道为什么，但尝试删除 
display
属性

如果您正在使用 table 并且遇到这个问题，那么 有两个对我有用的技巧。 我不知道这个技巧是否是正确的解决方案。

  1. 检查表格内所有 
    td
    中的 
    tr
    数量应相同。
  2. 如果您使用过 
    tfooter
    ，请移除 
    tfooter
    并将其放入 
    tr
    内。
    

    3. 它可能对你有帮助。

tbody






之后：






<thead>
<tr>
...
</tr>
</thead>
...






为我工作。
我没有发现，因为数据很少（10）工作正常，但数据更多（15-20）它返回了这个错误
