MPDF如何防止TD上的线路断裂

MPDF如何防止TD上的新线，我希望文本超过TD宽度，并且自动字符被“ ...”代替。例如： png

我试图计算每个字符占据的宽度，并使用'...''...拼接多余部分，但仍然无法满足要求，有些字符仍然会读取销售线 png png

php code

$config = [
    'mode' => 'utf-8',
    'margin_top' => 13,
    'margin_left' => 10,
    'margin_right' => 10,
    'format' => 'A4',
    'dpi' => 300,
];
$mpdf = new Mpdf($config);
$mpdf->autoScriptToLang = true;
$mpdf->autoLangToFont = true;
$html = file_get_contents('./test.html');
$mpdf->SetFont('sun-exta', null, 8.16);
$subStr2 = function (string $s) use ($mpdf) {
    $totalWidth = 167.11608661417;
    $w = 0;
    $dotWidth = 3 * $mpdf->GetCharWidthNonCore('.', false) * Mpdf::SCALE;
    $w += $dotWidth;
    for ($i = 0, $clen = mb_strlen($s); $i < $clen; $i ++) {
        $c = mb_substr($s, $i, 1, 'UTF-8');

        $cw = ($mpdf->GetCharWidthNonCore($c, false) * Mpdf::SCALE);
        $w += $cw;
        if ($w > $totalWidth) {
      
            return mb_substr($s, 0, $i, 'UTF-8') . '...';
        }

    return $s;

How does mpdf prevent newlines on td, I want the text to exceed the td width and the automatic characters are replaced with '...'
eg:
before png

I try to calculate the width occupied by each character, and use '...' to splicing the excess part, but it still can't meet the requirements, and some characters still read line break
after png

php code

$config = [
    'mode' => 'utf-8',
    'margin_top' => 13,
    'margin_left' => 10,

    'format' => 'A4',
    'dpi' => 300,
];
$mpdf = new Mpdf($config);
$mpdf->autoScriptToLang = true;
$mpdf->autoLangToFont = true;
$html = file_get_contents('./test.html');
$mpdf->SetFont('sun-exta', null, 8.16);
$subStr2 = function (string $s) use ($mpdf) {
    $totalWidth = 167.11608661417;
    $w = 0;
    $dotWidth = 3 * $mpdf->GetCharWidthNonCore('.', false) * Mpdf::SCALE;
    $w += $dotWidth;
    for ($i = 0, $clen = mb_strlen($s); $i < $clen; $i ++) {
        $c = mb_substr($s, $i, 1, 'UTF-8');

        $cw = ($mpdf->GetCharWidthNonCore($c, false) * Mpdf::SCALE);
        $w += $cw;
        if ($w > $totalWidth) {
      
            return mb_substr($s, 0, $i, 'UTF-8') . '...';
        }
