Do You Need To Style <tr> & <td>

[tomyknoker]

I was reading a tutorial were they always style both <tr> & <td> with the same thing... Is this needed? Or do you just need to style <tr>?

table.navigation tbody tr.odd {
	background: #252525;
	color: #fff;
	}
table.navigation tbody tr.odd td {
	background: #252525;
	color: #fff;
	}

I dont think that it is required under web standards, but it might be needed for IE. I might be wrong, but its just a guess
