我的输出
推荐答案
我遇到了同样的问题，这个问题的工程解决方案最终是魔术常量和 addPage 用法的组合，如果我的计算表明我们应该手动进行分页:
I was facing the same issue and engineering solution for this problem ended up as a combination of magic constants and usage of addPage if my calculation showed that we should do a manual page break:
$top_margin = 82;
[...]
if ($pdf->getY() > (300 /* A4 height */ - $top_margin + 40 /* another magic constant */)) {
$pdf->addPage();
}
写完每一行之后.在您的情况下，您可能需要调整常量，但这解决了我的问题.
After writing each row. In your case, you would probably need to adjust the constants, but this solved my problems.
看起来像一个错误，库愿意在页面区域的末尾写入.我不认为，我们可以解决这个问题，因为作者已经开始开发新的 PDF 库 tc-lib-pdf.
It looks like a bug, that the library is willing to write behind the end of the page region. I don't think, we can get this fixed, because author already moved to development of a new PDF library tc-lib-pdf.
