I have been trying to make a table in HTML with a fixed header (and a horizontal scrollbar when necessary). This JSFiddle shows what I have so far:

```
html, body {
    margin:0;
    padding:0;
    height:100%;
}

.horizontalscrollcontainer {
    position: relative;
    padding-top: 37px;
    overflow:auto;
}

.verticalscrollcontainer {
    background:transparent;
    overflow-y:auto;
    overflow-x:visible;
    height: 200px;
}
table {
    border-spacing: 0;
    width:120%;
}
td + td {
    border-left:1px solid #eee;
}
td, th {
    border-bottom:1px solid #eee;
    background: #ddd;
    color: black;
    padding: 10px 25px;
}
th {
    height: 0;
    line-height: 0;
    padding-top: 0;
    padding-bottom: 0;
    color: transparent;
    border: none;
    white-space: nowrap;
}
th div {
    position: absolute;
    background: transparent;
    color: black;
    padding: 9px 25px;
    top: 0px;
    margin-left: -25px;
    line-height: normal;
    border-left: 1px solid #800;
}
th:first-child div {
    border: none;
}

<div class="horizontalscrollcontainer">
    <div class="verticalscrollcontainer">
        <table>
            <thead>
                <tr class="header">
                    <th>Table attribute name
                        <div>Table attribute name</div>
                    </th>
                    <th>Value
                        <div>Value</div>
                    </th>
                    <th>Description
                        <div>Description</div>
                    </th>
                </tr>
            </thead>
            <tbody>
                <tr>
                    <td>align</td>
                    <td>left, center, right</td>
                    <td>Not supported in HTML5. Deprecated in HTML 4.01. Specifies the alignment of a table according to surrounding text</td>

                </tr>
            </tbody>
        </table>
    </div>
</div>

The problem I am having is that the horizontal scrollbar seems to go on the verticalscrollcontainer rather than the horizontalscrollcontainer. Is there any way to regulate this (the overflow-x is automatically set to auto because overflow-y is set to auto).

Thanks for any suggestions!
