点击时如何更改HTML表格单元格颜色
问题描述：
我试图在用户点击单元格时更改HTML表格单元格的背景颜色。任何想法如何做到这一点？我可以访问JS Prototype库，所以对Prototype或者直接Javascript的任何建议都会受到欢迎。
I'm trying to change the background color of an HTML table cell when the user clicks on the cell. Any ideas on how to do this? I have access to the JS Prototype library, so any suggestions for Prototype or straight Javascript would be welcome.

丑陋，但演示效果：
Ugly, but demonstrates the effect:
<table>
<tr>
<td onclick="this.style.backgroundColor = 'Red';">Sample</td>
<td onclick="this.style.backgroundColor = 'Blue';">Data</td>
</tr>
</table>
