How do you write this so it runs faster. It looks like because I'm using an each() it is slowing it down. 

Can I use filter()?

```
 $("#X tr").each(function () {       
     if ($(this).find("table td:eq(1)").text() == "a") {
         $(this).css("background":"red");    
  }

});   

     <table id = "X">
        <tr >
        <td>a</td>
        <td>b</td>
        <td>c</td>
        </tr>
        <tr >
        <td></td>
        <td></td>
        <td></td>
        </tr>
        ...
        <tr >
        <td>a</td>
        <td>b</td>
        <td>c</td>
        </tr>
   </table>

```

thanks
