查看我的动态 html 表格代码，它当前显示如下表格：
这显然是不正确的，它应该显示如下表：
我猜代码的标记有问题，但我似乎看不出问题出在哪里。有谁知道问题出在哪里才能获得正确的表格布局？PHP：
<?php
if (isset($_POST['id'])) {
$_SESSION['id'] = $_POST['id'];
}
$assessment = $_SESSION['id'];
include('connect.php');
$query = "SELECT q.SessionId, s.SessionName, q.QuestionId, q.QuestionContent, an.Answer, q.QuestionMarks
FROM Session s
INNER JOIN Question q ON s.SessionId = q.SessionId
JOIN Answer an ON q.QuestionId = an.QuestionId AND an.SessionId = q.SessionId
WHERE s.SessionName = ?
ORDER BY q.QuestionId, an.Answer";
// prepare query
$stmt=$mysqli->prepare($query);
// You only need to call bind_param once
$stmt->bind_param("s", $assessment);
// execute query
$stmt->execute();
// This will hold the search results
$searchQuestionId = array();
$searchQuestionContent = array();
$searchAnswer = array();
$searchMarks = array();
// Fetch the results into an array
// get result and assign variables (prefix with db)
$stmt->bind_result($dbSessionId, $dbSessionName, $dbQuestionId, $dbQuestionContent, $dbAnswer, $dbQuestionMarks);
while ($stmt->fetch()) {
$searchQuestionId[] = $dbQuestionId;
$searchQuestionContent[] = $dbQuestionContent;
$searchAnswer[] = $dbAnswer;
$searchMarks[] = $dbQuestionMarks;
}?>

下面是数组的 print_r 显示的内容：
数组 ( [0] => 1 [1] => 1 2 => 1 3 => 2 ) 数组 ( [0] => 命名 ROM 中的三个特征 [1] => 命名 ROM 中的三个特征2 =>命名 ROM 中的三个特征3 => 这是一个单一的答案 ) 数组 ( [0] => A [1] => B 2 => D 3 => True ) 数组 ( [0] => 5 [1] = > 5 2 => 5 3 => 5)
