Fitting a <fieldset> to the size of its content with CSS?

问题

Here's a fiddle.

I need to make the <fieldset> the width of its contents, rather than its parent. Is there a good way to do this?

HTML

<div>
   <form>
      <fieldset>
         <legend>Hey</legend>
         <table>
            <thead><tr><td>H1</td><td>H2</td></tr></thead>
            <tbody><tr><td>A1</td><td>B2</td></tr>
               <tr><td>A2</td><td>B9</td></tr></tbody>
         </table>
      </fieldset>
   </form>
</div>

CSS

fieldset{
   border: solid 2px blue;  
   float:left;
}
table{
   border: solid 2px red;   
}
div{
   width: 80%;   
   overflow:hidden;
   border: solid 2px purple;
   padding: 1em;
}
