我正在尝试使用数据表创建一个PDF文件。但是当遇到分页符时，每次在断点级别将新的多单元添加到页面时它会跳转到新页面。
我尝试使用TCPDF做同样的事情，但每次在分页点级别附近添加一个新单元时，页面中断的问题仍然相同...

答案 0 :(得分：20)
问题是在Cell()方法（在MultiCell()中调用）中，如果当前Y位置+新单元格的高度大于允许值，则FPDF总是添加新页面页面高度。
默认页面高度似乎为297，SetAutoPageBreak()会从中减去150。因此，当Y + cell_height比147更为鲜明时，您在调用cnstr_cell()时会获得新页面。
要防止这种情况，您需要自己致电AddPage()。在add_product()方法中添加此项检查：
$x = $this->width;
$y = $this->pdf->GetY();
if (($y + $this->line_height) >= 147) {
$this->pdf->AddPage();
$y = 0; // should be your top margin
}
顺便说一下。我最近也必须生成一个动态PDF，我最终使用wkhtmltopdf，它比所有PHP库更容易使用和自定义。我建议看看它。
