html - 表中的列在应用程序中未对齐

Question

我无法将表格中的列与其表格标题对齐，奇怪的是这里的 Jsfiddle 中对齐没有问题:http://jsfiddle.net/m4HB3/68/

但在我使用完全相同代码的应用程序中，它没有将列与其标题正确对齐:application

我的问题是我需要在应用程序中包含什么才能解决应用程序中的对齐问题？

代码如下:

HTML:

<table id="tableqanda" cellpadding="0" cellspacing="0">
    <thead>
    <tr>
        <th width="5%" class="questionno">Question No</th>
        <th width="23%" class="question">Question</th>
        <th width="7%" class="option">Option Type</th>
        <th width="6%" class="noofanswers">Number of Answers</th>
        <th width="7%" class="answer">Answer</th>
        <th width="6%" class="noofreplies">Number of Replies</th>
        <th width="6%" class="noofmarks">Number of Marks</th>
        <th width="11%" class="image">Image</th>
        <th width="11%" class="video">Video</th>
        <th width="11%" class="audio">Audio</th>
    </tr>
    </thead>
    </table>
    <div id="tableqanda_onthefly_container">
    <table id="tableqanda_onthefly" cellpadding="0" cellspacing="0">
    <tbody>
        <tr class="tableqandarow">
        <td width="5%" class="questionno">Question No.</td>
        <td width="23%" class="question">Question</td>
        <td width="7%" class="option">Option</td>
        <td width="6%" class="noofanswers">Number of Answers</td>
        <td width="7%" class="answer">Answer</td>
        <td width="6%" class="noofreplies">Number of Replies</td>
        <td width="6%" class="noofmarks">Number of Marks</td>
            <td width="11%" class="image"><ul><li>Image</li></ul></td>
        <td width="11%" class="video"><ul><li>Video</li></ul></td>
        <td width="11%" class="audio"><ul><li>Audio</li></ul></td>
</tr>
    </tbody>
    </table>
    </div>

CSS:

#tableqanda_onthefly_container
{
    max-height: 25px;
    width: 100%;
    overflow-y: scroll;
}


#tableqanda_onthefly
{
    width:100%;
    clear:both;
    table-layout: fixed;
}

#tableqanda_onthefly td
{
    border:1px black solid;
    border-collapse:collapse;
}

#tableqanda, #tableqanda_onthefly{
    border:1px black solid;
    border-collapse:collapse;
    word-wrap:break-word;
}       

#tableqanda{
    width:97%;
    margin-left:0;
    table-layout: fixed;
    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;
}

.tableqandarow{
    border:1px black solid;
    border-collapse:collapse;
}


.imagetd{
    font-size:75%;  
}

.audiotd{
    font-size:75%;  
}

.videotd{
    font-size:75%;  
}

.qandaul{
    list-style-type:square;
}

ul, ul li { margin: 0; padding: 0; }
ul { margin-left: 1.3em; }

您的列宽加起来不等于 100%；如果将其留给浏览器来解决，则无法确定对齐方式是否与您的想法相匹配。

将宽度更改为总和为 100%，您应该没问题。
