in a table field i am taking input as a file.

```
<table>
<tr>
<th>
<input type="file" name="icon" id="icon" />
</th> 
</tr>
</table>

```

It takes a size a 242-246px as width.

I declare :

```
<th width="50px"><input type="file" name="icon" id="icon" /></th>

```

But no changes occurred as size. Have any idea ?
