php - 使用多维数组构建具有 rowspan 的表

Question

我希望一周的学生和事件以日历格式显示。我有如下数组。每个学生有 7 个数组，从星期一到星期天，每个数组的内部都有当天的事件

$array = [
    'Alex' => [
        [
            ['event' => 'eventName1'],['event' => 'eventName2']
        ],
        [
            ['event' => 'eventName3'],['event' => 'eventName4']
        ],
        [
            ['event' => 'eventName5'],['event' => 'eventName6']
        ],
        [
            ['event' => 'eventName7'],['event' => 'eventName8']
        ],
        [],
        [],
        []

    ], 
    'Allen' => [
        [
            ['event' => 'eventName'],['event' => 'eventName']   
        ],[
            ['event' => 'eventName'],['event' => 'eventName']  
        ],
        [],
        [],
        [],
        [],
        []
    ],
];

我需要数组显示为周历， 我不知道下面的代码哪里出了问题

<table>
    <thead>
        <tr>
            <th>Participant</th>
            <th>Monday</th>
            <th>Tuesday</th>
            <th>Wednesday</th>
            <th>Thrusday</th>
            <th>Friday</th>
            <th>Satday</th>
            <th>Sunday</th>
        </tr>
    </thead>
    <tbody>
        <?php foreach ($array as $participant => $event): ?>
        <?php foreach ($event as $i => $value):?>
        <tr>
            <?php if ($i === 0): ?>
            <td rowspan="2"><?= $participant ?></td>
            <?php endif ?>
            <?php foreach ($value as $index  => $eventD):?>

            <td><?php echo $eventD['event']; ?></td>

        </tr>
        <?php endforeach ?>
        <?php endforeach ?>
        <?php endforeach ?>
    </tbody>
</table>

我的问题是循环以及如何打印特定日期的事件。 任何人都可以建立正确的格式。谢谢帮助
