在CodeIgniter中将多维数组单独显示为表行

<table>
    <thead>
        <tr>
            <th>Key</th>
            <th>Value</th>
        </tr>
    </thead>
    <tbody>
        <?php foreach ($array as $key => $value): ?>
            <?php if (is_array($value)): ?>
                <?php foreach ($value as $subKey => $subValue): ?>
                    <tr>
                        <td><?php echo $subKey; ?></td>
                        <td><?php echo $subValue; ?></td>
                    </tr>
                <?php endforeach; ?>
            <?php else: ?>
                <tr>
                    <td><?php echo $key; ?></td>
                    <td><?php echo $value; ?></td>
                </tr>
            <?php endif; ?>
        <?php endforeach; ?>
    </tbody>
