如何在PHP代码中使用foreach模式设置rowspan表

<?php
// 模拟数据
$data = [
    ['Name' => 'John', 'Age' => 20, 'Gender' => 'Male'],
    ['Name' => 'Alice', 'Age' => 18, 'Gender' => 'Female'],
    ['Name' => 'Bob', 'Age' => 22, 'Gender' => 'Male'],
    ['Name' => 'Alice', 'Age' => 25, 'Gender' => 'Female'],
    ['Name' => 'John', 'Age' => 30, 'Gender' => 'Male'],
];

// 初始化变量
$prevName = '';
$rowspan = 0;

// 输出表格开始标签
echo '<table>';

// 使用foreach循环遍历数据
foreach ($data as $row) {
    echo '<tr>';

    // 判断当前单元格的值是否与前一个单元格的值相同
    if ($row['Name'] == $prevName) {
        $rowspan++; // 相同则累加rowspan的值
    } else {
        if ($rowspan > 0) {
            echo '<td rowspan="' . $rowspan . '">' . $prevName . '</td>';
        }

        $prevName = $row['Name'];
        $rowspan = 1;
    }

    // 输出其他单元格
    echo '<td>' . $row['Age'] . '</td>';
    echo '<td>' . $row['Gender'] . '</td>';

    echo '</tr>';
}

// 输出最后一个单元格
if ($rowspan > 0) {
    echo '<td rowspan="' . $rowspan . '">' . $prevName . '</td>';
}

// 输出表格结束标签
echo '</table>';
?>
