关于表格的2个问题,输出如下:
问题1:
表高度是500px,但是我不明白的是,它看起来不属于表的下面的内容显示在表中,因为滚动条下降到它看起来就像表格行下面的内容一样。所以我的问题是如何才能让滚动条仅在满足500px的情况下出现,而不是像现在一样直接显示它?我如何获取内容(选择框,标题等)显示在表格下方而不是表格中,如屏幕截图所示
问题2:
如何将滚动条剪裁在桌子的一侧?目前它被剪切在最后一列的下方,这意味着它占据了最后一列的空间,因此表格列不匹配。
下面是表格的HTML代码:
<table id="tableqanda" align="center" cellpadding="0" cellspacing="0">
<thead>
<tr>
<th width="30%" class="question">Question</th>
<th width="8%" class="option">Option Type</th>
<th width="6%" class="noofanswers">Number of Answers</th>
<th width="8%" class="answer">Answer</th>
<th width="6%" class="noofreplies">Number of Replies</th>
<th width="6%" class="noofmarks">Number of Marks</th>
<th width="12%" class="images">Images</th>
</tr>
</thead>
</table>
<div id="tableqanda_onthefly_container">
<table id="tableqanda_onthefly" align="center" cellpadding="0" cellspacing="0">
<tbody>
<?php
foreach ($arrQuestionContent as $key=>$question) {
echo '<tr class="tableqandarow">'.PHP_EOL;
echo '<td width="30%" class="question">'.htmlspecialchars($question).'</td>' . PHP_EOL;
echo '<td width="8%" class="option">'.htmlspecialchars($arrOptionType[$key]).'</td>' . PHP_EOL;
echo '<td width="6%" class="noofanswers">'.htmlspecialchars($arrNoofAnswers[$key]).'</td>' . PHP_EOL;
echo '<td width="8%" class="answers">'.htmlspecialchars($arrAnswer[$key]).'</td>' . PHP_EOL;
echo '<td width="6%" class="noofreplies">'.htmlspecialchars($arrReplyType[$key]).'</td>' . PHP_EOL;
echo '<td width="6%" class="noofmarks">'.htmlspecialchars($arrQuestionMarks[$key]).'</td>' . PHP_EOL;
echo '<td width="12%" class="images">'.htmlspecialchars($arrImageFile[$key]).'</td>' . PHP_EOL;
echo '</tr>'.PHP_EOL;
}
?>
</tbody>
</table>
<h4>PARTICIPATING STUDENTS</h4>
<p>
<strong>Number of Participating Students:</strong> <?php echo $studentnum; ?>
</p>
<p>
<strong>Current Participating Students:</strong>
<br/>
<tr>
<td>
<select name="students" id="studentslist" size="10">
<?php
if($studentnum == 0){
echo "<option disabled='disabled' class='red' value=''>No Students currently in this Assessment</option>";
}else{
while ( $currentstudentstmt->fetch() ) {
echo "<option disabled='disabled' value='$dbStudentId'>" . $dbStudentAlias . " - " . $dbStudentForename . " " . $dbStudentSurname . "</option>" . PHP_EOL;
}
}
?>
</select>
</p>
下面是CSS:
#tableqanda_onthefly_container
{
width:100%;
overflow-y: scroll;
overflow-x: hidden;
max-height:500px;
}
#tableqanda_onthefly
{
width:100%;
overflow:auto;
clear:both;
}
#tableqanda, #tableqanda_onthefly{
border:1px black solid;
border-collapse:collapse;
table-layout:fixed;
}
#tableqanda{
width:100%;
margin-left:0;
float:left;
}
#tableqanda td {
vertical-align: middle;
border:1px black solid;
border-collapse:collapse;
}
#tableqanda th{
border:1px black solid;
border-collapse:collapse;
text-align:center;
}
我希望我的表格保持为带有固定标题的滚动表
答案 0 :(得分:0)

对于问题1,请尝试将overflow-y属性设置为auto。这样,只有当表格的高度超过500px时,才会显示滚动条。
类似于:
overflow-y:auto;
而不是
overflow-y:scroll;

要回答第二个问题,您可以将表格的头部添加为另一行:
<div id="tableqanda_onthefly_container">
<table id="tableqanda_onthefly" align="center" cellpadding="0" cellspacing="0">
<tr>
<th width="30%" class="question">Question</th>
<th width="8%" class="option">Option Type</th>
<th width="6%" class="noofanswers">Number of Answers</th>
<th width="8%" class="answer">Answer</th>
<th width="6%" class="noofreplies">Number of Replies</th>
<th width="6%" class="noofmarks">Number of Marks</th>
<th width="12%" class="images">Images</th>
</tr>
<?php
foreach ($arrQuestionContent as $key=>$question) {
echo '<tr class="tableqandarow">'.PHP_EOL;
echo '<td width="30%" class="question">'.htmlspecialchars($question).'</td>' . PHP_EOL;
echo '<td width="8%" class="option">'.htmlspecialchars($arrOptionType[$key]).'</td>' . PHP_EOL;
echo '<td width="6%" class="noofanswers">'.htmlspecialchars($arrNoofAnswers[$key]).'</td>' . PHP_EOL;
echo '<td width="8%" class="answers">'.htmlspecialchars($arrAnswer[$key]).'</td>' . PHP_EOL;
echo '<td width="6%" class="noofreplies">'.htmlspecialchars($arrReplyType[$key]).'</td>' . PHP_EOL;
echo '<td width="6%" class="noofmarks">'.htmlspecialchars($arrQuestionMarks[$key]).'</td>' . PHP_EOL;
echo '<td width="12%" class="images">'.htmlspecialchars($arrImageFile[$key]).'</td>' . PHP_EOL;
echo '</tr>'.PHP_EOL;
}
?>
</table>
</div>
这样滚动条应该放在最右边,而不是放在任何东西下面。它不是之前的原因是因为你有两个不同宽度的表。
