Dompdf cellmap.php uncaught error !

Guys I think i might found a solution for this error. If u got the error like below...just go to the line stated and change [$key] to [$g_key]. It might solve your problem.

Fatal error: Uncaught Dompdf\Exception: The row #4 could not be found, please file an issue in the tracker with the HTML code in D:\xampp\htdocs\sistem\programme\mysql\dompdf\src\Cellmap.php:415

$rows = $this->_frames[$key]["rows"];
        $h = 0;
        foreach ($rows as $i) {
            if (!isset($this->_rows[$i])) {

to

$rows = $this->_frames[$g_key]["rows"];
        $h = 0;
        foreach ($rows as $i) {
            if (!isset($this->_rows[$i])) {


In my case, this happened because the border is hidden when there's is no data. The row is empty so i put in my code when it is empty, it displays nothing (none).

Drop your comments below if it works and let others know....
