如果列运行离开页面，如何将由数据库数据生成的 html table 分隔在其自身下方？

Question

下面是 HTML table 系统地从 MySQL 数据库生成并使用 TCPDF 生成的。每列都是根据用户输入的分析数量生成的。如图所示，一旦列数超过页面的容量，系统地创建 table 就会成为一个问题。

我想做的是只允许生成 4 列，然后附加相应的结果，如图所示，然后在第一个 table 下方生成第二个和接下来的 4 列，依此类推在。

有谁知道可以做到这一点的简单方法吗？

如果没有简单的方法，那么操纵 PHP 代码是唯一的选择。我不允许显示整个代码（客户的要求），但是，我可以显示生成列的部分。

中的$micro_analysis是以逗号分隔的数字，如：1,2,3,4对应一个主键，即分析名，从tablemicrobiology_analysis_database，就增加一些清晰度。

听起来你想使用 array_chunk 函数，然后循环遍历结果数组，如下所示：

    $sqla = "SELECT * FROM samples_database WHERE order_id=$order_id AND sample_group='$group' AND $analysis!='';";
    $resulta = mysqli_query($conn, $sqla);

    $sqlb = "SELECT * FROM samples_database WHERE order_id=$order_id AND sample_group='$group' AND $analysis!='';";
    $resultb = mysqli_query($conn, $sqlb);


    $micro_analysis = '';
    while($input = mysqli_fetch_array($resultb)) {
        $micro_analysis .= $input[$analysis] . ',';
    }

    $micro_analysis_arr = array_filter(array_unique(explode(',', $micro_analysis)));

    $array_size = count($micro_analysis_arr);

    // Chunk the array into smaller parts
    $tables = array_chunk($micro_analysis_arr, 4);

    if (mysqli_num_rows($resulta) > 0) {

        // Loop through 4-part arrays as unique tables
        foreach($tables as $table) {

        $html .= '
        <table border="1" cellspacing="0" cellpadding="3">      
        <thead>
        <tr>';
        //<th><strong>Lab ID</strong></th>
        $html .= '<th width="200px"><strong>Client ID</strong></th>';

        foreach ($table as $row1) {
            $query = "SELECT * FROM microbiology_analysis_database WHERE id=$row1 AND analysis_type='$analysis_type';"; 
            $resultc = mysqli_query($conn, $query);
            $inputc = mysqli_fetch_array($resultc);


            if (empty($inputc['analysis_sample_type'])) {
                $html .= '<th style="text-align:center;"><strong>'.$inputc['analysis_name'].'<br /> ('.$inputc['analysis_unit'].')</strong></th>';
            } else {
                $html .= '<th style="text-align:center;"><strong>'.$inputc['analysis_name'].'<br /> ('.$inputc['analysis_unit'].')</strong></th>';
            }
        }

                    $micro_analysis2 = '';

                    while($input = mysqli_fetch_array($result3)) {

                        } else {

                            $result5 = mysqli_query($conn, $query5);
