Question

我使用TCPDF输出一个html表，在我的例子中这个不是我必须修改的唯一一个，所以我需要一些规则来呈现我的页面。到目前为止，TCPDF在我看来是一个强大的库，所以我希望不要尝试另一个。

我的问题是，我需要将表格标题添加到表格所显示的每个新页面，但我还有其他信息要写入此pdf，不得有表头，所以我不能使用重写tcpdf中的header方法。

<table border="0" cellspacing="0" cellpadding="0" align="center" width="100%" ><tr><td><table border="0" cellspacing="0" cellpadding="3" align="left" width="100%" ><tr><td class="TableHeader"  width="5%" style="padding: 5px;

我想到了以下解决方案：如果不知怎的话我可以将这个html拆分为行并逐行写入pdf，以便我可以回滚当我在页脚上写，然后我添加一个新页面，但是有一个主要的问题，我得到各种警告，因为html表标签没有关闭。这是我的代码：

$pdf->setAutoPageBreak(false);
$pdf->startTransaction();
$html = new simple_html_dom();
$html->load($data);
$single = $html->find('#Container', 0);
if($single){

 $rows = $single->getElementsByTagName('tr');
 $rows = $rows[0]->getElementsByTagName('tr');

 if($rows)
   for($i=1;$i<(count($rows)-1);$i++){
     $pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', '<table>', $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
     $pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', $rows[$i]->outertext, $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
     $pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', '</table>', $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);

   if ($pdf->getY() > $pdf->getPageHeight() - 30) {
       $pdf->rollbackTransaction(true);
       $pdf->AddPage();
       $pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', '<table>', $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
       $pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', $rows[$i]->outertext, $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
       $pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', '</table>', $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
        }
    }
   }


    $pdf->commitTransaction();
    $pdf->setAutoPageBreak(true, 30);

我快速浏览了这两篇文章，也许有人会发现这个方便： Some paging with multicell 和Another paging with multicell。我发现这个2值得一个例子作为解决方案逻辑，但与tcpdf一起使用的方法在我看来有点奇怪。

我认为您的解决方案很好。只有我能想到的其他方法是使用固定宽度的多单元，这可能会非常痛苦，但会给你静态的列宽。

但是我注意到了一些问题：

您的事务包装整个文档，回滚应该将文档重置为空。
您的警告可能是因为您传递的部分HTML代码无法呈现为writeHTMLCell。（你只传递＆lt; table＆gt;或＆lt; / table＆gt;单独使用时，无法呈现）
如果您在表格标签中包装每一行，您的列就不会排成一行。最好的办法是将该页面上的行包装在表格块中。

尝试这些更改，让我知道它是怎么回事

$pdf->setAutoPageBreak(false);
//$pdf->startTransaction(); // Moved
$html = new simple_html_dom();
$html->load($data);
$single = $html->find('#Container', 0);
if($single){

    $rows = $single->getElementsByTagName('tr');
    $rows = $rows[0]->getElementsByTagName('tr');

    if($rows) {
        $pdf->startTransaction(); // Start transaction only because we may need it
        // Header for html, this starts the html and can optionally insert the header row as the first row on every new page.
        $html_header = '<tr><td>Name</td><td>Age</td></tr>'; 
        $html_buffer = '<table>'.$html_header;
        for($i=1;$i<(count($rows)-1);$i++){
            $pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', $html_buffer.$rows[$i]->outertext.'</table>', $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);

            if ($pdf->getY() < ($pdf->getPageHeight() - 30)) { // Note the less-than operator
                // We might be able to add some more text, so undo that
                $pdf->rollbackTransaction(true);
                // And store the html
                $html_buffer .= $rows[$i]->outertext;
            }else{
                // We exceeded our limit
                $pdf->rollbackTransaction(true);
                // Write last known good table
                $pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', $html_buffer.'</table>', $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
                // Add a new page
                $pdf->AddPage();
                // End this transaction
                $pdf->commitTransaction();
                // Start a new transaction
                $pdf->startTransaction();
                // Reset html buffer
                $html_buffer = '<table>'.$html_header;
                // Add line we couldn't fit on last page to html buffer
                $html_buffer .= $rows[$i]->outertext;
            }
        }
        // There is still information in our buffer and it fits on a single page
        $pdf->writeHTMLCell($w=0, $h=0, $x='', $y='', $html_buffer.'</table>', $border=0, $ln=1, $fill=0, $reseth=true, $align='', $autopadding=false);
        // Final commit
        $pdf->commitTransaction(); 
    }
}
$pdf->setAutoPageBreak(true, 30);

这会将页面上的所有内容包装在表格块中，以便列在该页面上排成一行。（但是，它们在页面之间可能仍然不同）另外，我让你能够像你想要的那样为每个新页面添加你自己的标题。只需将$ html_header更改为您自己的标题行代码。

当你说TCPDF令人困惑时，你说得对，但它也非常强大，一旦掌握了它，你就可以制作一些非常好的文档。

转到TCPDF并选择Example 48，您会看到一个带有<thead>元素的示例。
