如何解决PDFLibPHP无法放置表格：计算的表格高度太大
我收到此异常：
无法放置桌子：计算出的桌子高度657.375过大（> 492，缩小了74.8432％）
内容是动态的，似乎有时它已经超出了表的容量，但是我不确定，有什么想法吗？
PDFLibary 9.2.0的版本/ PHP 7.2.13 MSVC15的版本
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());
