well, I actually fixed it by not having border-collapse. I hate this fix. If anyone can help me do it in a cleaner way, I'd appreciated.

Here's the fixed and tweaked CSS:

#Search_Result {
	width: 980px; min-width: 980px; max-width: 980px;
	margin: 0 auto; margin-bottom: 10px;
	background-color: #fff;
}	#Search_Result table { 
		width: 100%; 
		background-color: #fff;
		border-collapse: separate;
		border-spacing: 0px;
	}	#Search_Result th {
			padding: 10px;
			font-size: 13px; color: #fff;
			border: 1px solid rgb(200,200,200);
			border-right: 0px;
			background: rgb(135,135,135); /* Old browsers */
			background: -moz-linear-gradient(top,  rgba(135,135,135,1) 0%, rgba(91,91,91,1) 100%); /* FF3.6+ */
			background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(135,135,135,1)), color-stop(100%,rgba(91,91,91,1))); /* Chrome,Safari4+ */
			background: -webkit-linear-gradient(top,  rgba(135,135,135,1) 0%,rgba(91,91,91,1) 100%); /* Chrome10+,Safari5.1+ */
			background: -o-linear-gradient(top,  rgba(135,135,135,1) 0%,rgba(91,91,91,1) 100%); /* Opera 11.10+ */
			background: -ms-linear-gradient(top,  rgba(135,135,135,1) 0%,rgba(91,91,91,1) 100%); /* IE10+ */
			background: linear-gradient(top,  rgba(135,135,135,1) 0%,rgba(91,91,91,1) 100%); /* W3C */
			filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#878787', endColorstr='#5b5b5b',GradientType=0 ); /* IE6-9 */
		} 	#Search_Result th:first-of-type { border-radius: 10px 0px 0px 0px; }		
			#Search_Result th:last-of-type { border-radius: 0px 10px 0px 0px; border-right: 1px solid rgb(200,200,200); }
	#Search_Result td { 
		padding: 2px; 
		border: 1px solid rgb(200,200,200); 
		border-right: 0px;	border-top: 0px;
	}	#Search_Result td:last-of-type { border-right: 1px solid rgb(200,200,200); }
