生成的序列号复制到剪贴板按钮

如何解决生成的序列号复制到剪贴板按钮

我正在向客户出售序列号，而他们大多是移动用户时遇到麻烦，他们难以手动复制文本，我想将复制按钮添加到从数据库生成的序列号到数据表中，以便客户可以用仅点击按钮

这是我的代码：

<?PHP defined( 'ABSPATH' ) || exit(); ?>
<?PHP global $serial_numbers; ?>
<?PHP echo sprintf( '<h2 class="woocommerce-order-downloads__title">%s</h2>',esc_html( $heading ) ); ?>

<table class="wcsn-order-table" cellspacing="0" style="width: 100%; font-family: 'Helvetica Neue',Helvetica,Roboto,Arial,sans-serif; margin-bottom: 40px;" border="1">
    <thead>
    <tr>
        <?PHP echo sprintf( '<th class="td" scope="col" style="text-align:left;">%s</h2>',html_entity_decode( $product_column ) ); ?>
        <?PHP echo sprintf( '<th class="td" scope="col" style="text-align:left;">%s</h2>',html_entity_decode( $content_column ) ); ?>
    </tr>
    </thead>

    <tbody>
    <?PHP foreach ( $serial_numbers as $serial_number ): ?>
        <tr>
            <td class="td" style="text-align:text-align:left;">
                <?PHP
                $product_column_content = html_entity_decode( $product_column_content );
                $product_column_content = str_replace( '{product_url}',esc_url( get_permalink( $serial_number->product_id ) ),$product_column_content );
                $product_column_content = str_replace( '{product_title}',get_the_title( $serial_number->product_id ),$product_column_content );
                echo $product_column_content;
                ?>
            </td>

            <td class="td" style="text-align:text-align:left;">
                <?PHP
                $serial_column_content = str_replace( '{serial_number}',\PluginEver\SerialNumbers\Helper::decrypt( $serial_number->serial_key ),html_entity_decode( $serial_column_content ) );
                $serial_column_content = str_replace( '{activation_email}',$order->get_billing_email(),$serial_column_content );
                $serial_column_content = str_replace( '{expired_at}',\PluginEver\SerialNumbers\Helper::get_expiration_date( $serial_number ),$serial_column_content );
                $serial_column_content = str_replace( '{activation_limit}',\PluginEver\SerialNumbers\Helper::get_activation_limit( $serial_number ),$serial_column_content );
                echo $serial_column_content;
                ?>
            </td>

        </tr>
    <?PHP endforeach; ?>
    </tbody>
