[Orgmode] Alternate Table Row Colors

[Xin Shi]

Hello Experts,

I use org-mode to produce a lot of big tables with numbers in them. When I present these tables by HTML, I found it's hard to keep track which row it is. I'm wondering if it's possible to implement additional class attribute to the <tr>, such as: 
 
<table class="sample">
<tr class="d0"><td>One</td><td>Fish</td></tr>
<tr class="d1"><td>Two</td><td>Fish</td></tr>
<tr class="d0"><td>Red</td><td>Fish</td></tr>
<tr class="d1"><td>Blue</td><td>Fish</td></tr>
</table>

So, that in the CSS file, it'll be easier to implement the color:

<style type="text/css">
table.sample {
	border: 6px inset #8B8378;
	-moz-border-radius: 6px;
}
table.sample td {
	border: 1px solid black;
	padding: 0.2em 2ex 0.2em 2ex;
	color: black;
}
table.sample tr.d0 td {
	background-color: #FCF6CF;
}
table.sample tr.d1 td {
	background-color: #FEFEF2;
}
</style>

I borrowed idea from this article:

Thanks!
