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头添加到表格显示的每个新页面,但我还有其他信息写入此pdf,必须没有表头,所以我不能使用重写头方法TCPDF. <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;

$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,$rows[$i]->outertext,'</table>',$autopadding=false);
if ($pdf->getY() > $pdf->getPageHeight() - 30) {
$pdf->rollbackTransaction(true);
$pdf->AddPage();
$pdf->writeHTMLCell($w=0,$autopadding=false);
$pdf->writeHTMLCell($w=0,$autopadding=false);
}
}
}
$pdf->commitTransaction();
$pdf->setAutoPageBreak(true,30);
我快速浏览了这2篇文章,也许有人会发现这个方便： 解决方法
我认为你的解决方案很好.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.
但是我发现了一些问题： >您的事务包装整个文档,回滚应该将文档重置为空. 尝试这些更改,让我知道它是如何进行的 $pdf->setAutoPageBreak(false);
//$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,$html_buffer.$rows[$i]->outertext.'</table>',$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,$html_buffer.'</table>',$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,$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即可. 当你说TCPDF令人困惑但你也是非常强大的时候你是对的,一旦掌握了它,你就可以制作一些非常好的文档. （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
