<table >
<tr class="odd First"><td>1one Cell</td><td>2one Cell</td><td>3one Cell</td><td>4one Cell</td> </tr>
<tr class="even Second"><td>Two Cell</td><td>2Two Cell</td><td>3Two Cell</td><td>4Two Cell</td></tr>
<tr class="odd Thrid"><td>1Three Cell</td><td>2Three Cell</td><td>3Three Cell</td><td>4Three Cell</td></tr>
<tr class="even Fourth"><td>1Five Cell</td><td>2Five Cell</td><td>3Five Cell</td><td>4Five Cell</td></tr>
</table>
我怎样才能得到 tr 的类名。请给我建议。
