<p>I am writing a page where I need an HTML table to maintain a set size. I need the headers at the top of the table to stay there at all times but I also need the body of the table to scroll no matter how many rows are added to the table. Think a mini version of excel. This seems like a simple task but almost every solution I have found on the web has some drawback. How can I solve this?</p>

Have you tried using thead and tbody, and setting a fixed height on tbody with overflow:scroll?
What are your target browsers?
EDIT: It worked well (almost) in firefox - the addition of the vertical scrollbar caused the need for a horizontal scrollbar as well - yuck.  IE just set the height of each td to what I had specifed the height of tbody to be.  Here's the best I could come up with:
```
```
<html>
    <head>
    <title>Blah</title>
    <style type="text/css">
    table { width:300px; }
    tbody { height:10em;  overflow:scroll;}
    td { height:auto; }
    </style>
    </head>
    <body>
    <table>
        <thead>
            <tr>
              <th>One</th><th>Two</th>
              </td>
            </tr>
        </thead>
        <tbody>
            <tr><td>Data</td><td>Data</td></tr>
            <tr><td>Data</td><td>Data</td></tr>
            <tr><td>Data</td><td>Data</td></tr>
            <tr><td>Data</td><td>Data</td></tr>
            <tr><td>Data</td><td>Data</td></tr>
            <tr><td>Data</td><td>Data</td></tr>
            <tr><td>Data</td><td>Data</td></tr>
            <tr><td>Data</td><td>Data</td></tr>
            <tr><td>Data</td><td>Data</td></tr>
            <tr><td>Data</td><td>Data</td></tr>
            <tr><td>Data</td><td>Data</td></tr>
            <tr><td>Data</td><td>Data</td></tr>
            <tr><td>Data</td><td>Data</td></tr>
            <tr><td>Data</td><td>Data</td></tr>
            <tr><td>Data</td><td>Data</td></tr>
        </tbody>
    </table>
    </body>
</html>
```
```
