I have an application here: Application

In the application please do the following:

1. You will see a green plus button on left hand side, click on it and it will open up a modal window.

2. In the search bar in the modal window type in the phrase single and submit search. A table will be shown below.

3. Add a row from the table by clicking on the "Add" button, it will add the information in the top controls.

4. Finally click on the "Add Question" button, this will append a table row underneath.

Now the issue I have is that the columns in the <thead> and the columns in the <tbody> does not match. What my question is that how can I get these columns to match?

HTML code is below showing the appended rows:

    var $tbody = $('#qandatbl > tbody'); 
    var $tr = $("<tr class='optionAndAnswer' align='center'>");
    var $td = $("<td class='extratd'>");
    var $plusrow = $("<td class='plusrow'></td>");
    var $qid = $("<td class='qid'></td>").text(qnum);
    var $question = $("<td class='question'></td>");
    var $noofanswers = $("<div class='noofanswers'>2. Number of Answers:<br/></div>");
    var $options = $("<div class='option'>1. Option Type:<br/></div>");
    var $answer = $("<div class='answer'>3. Answer:<br/></div>");
    var $replies = $("<td class='noofreplies'><div class='wrapper'></div></td>");
    var $weight = $("<td class='weight'></td>");
    var $image = $("<td class='image'></td>"); 
    var $video = $("<td class='video'></td>");
    var $audio = $("<td class='audio'></td>");

...

    $tr.append($plusrow);
    $tr.append($qid);
    $tr.append($question);
    $tr.append($td);
    $td.append($options);
    $td.append($noofanswers);
    $td.append($answer);
    $tr.append($replies);
    $tr.append($weight);   
    $tr.append($image);  
    $tr.append($video);
    $tr.append($audio);
    $tbody.append($tr); 

Below is the html table where it contains the table headings columns and where the table rows are appended to:

<table id="qandatbl" align="center">
<thead class="tblhead">
<tr>
    <th></th>
    <th class="qid">Question No</th>
    <th class="question">Question</th>
    <th class="optandans">Option and Answer</th>
    <th class="noofreplies">Number of Replies</th>
    <th class="weight">Number of Marks</th>
    <th class="image">Image</th>
    <th class="video">Video</th>
    <th class="audio">Audio</th>
</tr>
</thead>
<tbody class="tblbody">
</tbody>
</table>

    overflow: auto;
    width:100%; 
}

.extratd{

}

.qid { 
    min-width:3%;
    max-width:3%;
    font-weight:bold;
    border:1px black solid;
    border-collapse:collapse;

    border:1px black solid;
    border-collapse:collapse;
    }

.answer { 
    min-width:100%;
    max-width:100%;
    padding-top:5%;
    padding-bottom:5%;
     }

.audio{

    }

.image{
    min-width:11%;
    max-width:11%;
    border:1px black solid;
    border-collapse:collapse;
    position:relative;
    }

.plusrow{
    min-width:2%;
    max-width:2%;
    border:1px black solid;
    border-collapse:collapse;
    }

The first answer (user1721135) is incorrect, it's because you've assigned the thead and tbody a display of "block". Remove that and your problem will disappear.

He is right that you don't have to assign a mix and a max-width if they are the same, but that's not what is causing your issue.
