How Can I Freeze HTML Table Headers Using CSS and JavaScript?

CSS and JavaScript Techniques for Fixed HTML Table Headers

The ability to freeze column headings in an HTML table, as seen in Microsoft Excel's "freeze panes" feature, is highly desirable for extended tables. There are several cross-browser techniques that can achieve this effect using either CSS or JavaScript.

CSS Transform Technique

For modern browsers, CSS transforms offer a simple and effective solution:

   var translate = "translate(0," this.scrollTop "px)";<br>   this.querySelector("thead").style.transform = translate;<br>});<br>

This code listens for scroll events on the table container and translates the table header (thead) based on the scroll position.

Advantages of CSS Transform Technique:

Minimal code (four lines)
No external dependencies
Works with various table configurations (table-layout)
Supports all major browsers except Internet Explorer 8-

Example Implementation:

   var translate = "translate(0," this.scrollTop "px)";<br>   this.querySelector("thead").style.transform = translate;<br>});

 Your existing container </em>/</p><h1>wrap {</h1><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">overflow: auto;
height: 400px;

Copy after login

}

/ CSS for demo /
td {

background-color: green;
width: 200px;
height: 100px;

Copy after login

}

<pre class="brush:php;toolbar:false"><table>
    <thead>
        <tr>
            <th>Foo</th>
            <th>Bar</th>
        </tr>
    </thead>
    <tbody>
        <tr><td></td><td></td></tr>
        <tr><td></td><td></td></tr>
        <tr><td></td><td></td></tr>
        <tr><td></td><td></td></tr>
        <tr><td></td><td></td></tr>
        <tr><td></td><td></td></tr>
        <tr><td></td><td></td></tr>
        <tr><td></td><td></td></tr>
        <tr><td></td><td></td></tr>
        <tr><td></td><td></td></tr>
        <tr><td></td><td></td></tr>
        <tr><td></td><td></td></tr>
    </tbody>
