我正在使用 php、pear HTML_Table 和 sql 构建动态表。我的第一个查询提取表头的信息，然后 pear 使用它来创建表头。下一个查询从多个表中提取信息以返回正确的数据集。接下来，我需要将这些数据集与标题联系起来，并在每个匹配列的下方显示结果。我能够显示所有数据，但不能正确显示。第 0 列从第 1 行开始，显示当前的 4 个测试项目，第 1 列从第 5 行开始，显示当前的 2 个测试项目，第 2 列然后从 7 开始...如何让列数重置为 0上一列的匹配数据用完了？这个问题的另一部分是我还需要将 rowSpan 应用于插入的数据，因为这是一个调度项目。我已经在这里待了一周，但找不到任何相关的例子或建议。我错过了什么，因为我认为这不应该是一项艰巨的任务？代码如下。

<?php
    session_start();
    include_once("../php/functions.php");

    $table = new HTML_Table($attrs);

好的，问题是我离开初始循环后没有增加 rowcounter 变量。以下行：

 $cellPosition++;
            $rowCounter = 1;
            $headerCounter++;
            $table->setCellContents($rowCounter,$cellPosition,$row['newField']);

本来应该：

 $cellPosition++;
            $rowCounter = 1;
            $headerCounter++;
            $table->setCellContents($rowCounter++,$cellPosition,$row['newField']);

很抱歉原始帖子的格式不佳。我不确定出了什么问题。
