How to make fixed header table inside scrollable div?

Question

I want to make header of my table fixed. Table is present inside the scrollable div. Below is my code.

<div id="table-wrapper">
    <div id="table-scroll">
        <table bgcolor="white" border="0" cellpadding="0" cellspacing="0" id="header-fixed" width="100%" overflow="scroll" class="scrollTable">
            <thead>
                <tr>
                    <th>Order ID</th>
                    <th>Order Date</th>
                    <th>Status</th>
                    <th>Vol Number</th>
                    <th>Bonus Paid</th>
                    <th>Reason for no Bonus</th>
                </tr>
            </thead>
            <tbody>
                <tr>
                    <td><%=snd.getOrderId()%></td>
                    <td><%=snd.getDateCaptured()%></td>
                    <td><%=snd.getOrderStatus()%></td>
                    <td>Data Not Available</td>
                    <td>Data Not Available</td>
                    <td>Data Not Available</td>
                </tr>
            </tbody>
        </table>
    </div>
</div>

Below is my CSS, which I am using for the above div:

#table-wrapper {
    position:relative;
}

#table-scroll {
    height:250px;
    overflow:auto;  
    margin-top:20px;
}

#table-wrapper table {
    width:100%;
}

#table-wrapper table * {
    background:white;
    color:black;
}

#table-wrapper table thead th .text {
    position:absolute;   
    top:-20px;
    z-index:2;
    height:20px;
    width:35%;
    border:1px solid red;
}

Answer 1

How about doing something like this? I've made it from scratch...

What I've done is used 2 tables, one for header, which will be static always, and the other table renders cells, which I've wrapped using a div element with a fixed height, and to enable scroll, am using overflow-y: auto;

Also make sure you use table-layout: fixed; with fixed width td elements so that your table doesn't break when a string without white space is used, so inorder to break that string am using word-wrap: break-word;

Demo

.wrap {
    width: 352px;
}

.wrap table {
    width: 300px;
    table-layout: fixed;
}

table tr td {
    padding: 5px;
    border: 1px solid #eee;
    width: 100px;
    word-wrap: break-word;
}

table.head tr td {
    background: #eee;
}

.inner_table {
    height: 100px;
    overflow-y: auto;
}

<div class="wrap">
    <table class="head">
        <tr>
            <td>Head 1</td>
            <td>Head 1</td>
            <td>Head 1</td>
        </tr>
    </table>
    <div class="inner_table">
        <table>
        <tr>
            <td>Body 1</td>
            <td>Body 1</td>
            <td>Body 1</td>
        </tr>
        <!-- Some more tr's -->
    </table>
    </div>
</div>

Answer 2

Using position: sticky on th will do the trick.

Note: if you use position: sticky on thead or tr, it won't work.

Some of these answers seem unnecessarily complex. Make your tbody:

display: block; height: 300px; overflow-y: auto

Then manually set the widths of each column so that the thead and tbody columns are the same width. Setting the table's style="table-layout: fixed" may also be necessary.
