css - Applying a single background gradient to a table row

Question

Is it possible to have a background gradient that spans an entire table row? I'm only able to apply the background to individual table cells, even when I'm specifically trying to prevent that. Here is a boiled-down sample that targets Webkit on jsfiddle:

As you can see, I am using border-collapse:collapse and I am specifying background:transparent for the <tr> and <th> child elements, yet the red gradient to the left is repeated for each table cell. I've tried applying the background to the <tr> as well, but with the same result as you see now.

To view the code without going to jsfiddle, here it is:

html

<table>
    <thead>
        <tr>
            <th>One</th>
            <th>Two</th>
            <th>Three</th>
            <th>Four</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>un</td>
            <td>deux</td>
            <td>trois</td>
            <td>quatre</td>
        </tr>
    </tbody>
</table>

css

* {margin:0;padding:0;border:0;border-collapse:collapse;}
table { width:100%; }
thead { background: -webkit-linear-gradient(left, rgba(222,22,22,1) 0%, rgba(222,222,222,0) 20%, rgba(222,222,222,0) 80%, rgba(222,222,222,1) 100%); }
thead tr, thead th { background:transparent; }

Answer 1

set background-attachment:fixed; on thead and it will work fine
