When the status is open the background would remain white, so if the status change to closed, i'd like to make the background green.Any idea.Thank you

```html
<table border='1' cellpadding='25'>

<th>Status</th>
<tr><td><select><option value="">Open</option><option value="">Closed</option></select></td></tr><br>
<tr><td><select><option value="">Open</option><option value="">Closed</option></select></td></tr><br>
<tr><td><select><option value="">Open</option><option value="">Closed</option></select></td></tr><br>
</table>
```
