php - PDFLib (PHP) 无法放置表格：计算的表格高度太大
问题描述
我得到这个例外：
无法放置表格：计算的表格高度 657.375 太大（> 492，缩小 74.8432%）
内容是动态的，有时它似乎超出了表格的容量，但我不确定，有什么想法吗？
PDFLibary 9.2.0 版本/PHP 7.2.13 MSVC15 版本
引发异常的代码部分：
$result = $p->fit_table($tbl, $llx, $lly, $urx, $y, $fit_opts);
if ($result == "_error")
throw new Exception("Couldn't place table : " .
$p->get_errmsg());
