Table borders still showing up despite style declarations

Note the lines on the table in this post:

I have put the following css into the stylesheet of my child theme and am still getting weird lines:

table{
	border-width: 0px;
	border-spacing: 0px;
	border-style: none;
	border-color: white;
	border-collapse: collapse;
	background-color: white;
}
table th {
	border-width: 0px;
	padding: 0px;
	border-style: none;
	border-color: white;
	background-color: white;
}
table td {
	border-width: 0px;
	padding: 0px;
	border-style: none;
	border-color: white;
	background-color: white;
}

Despite this code, I still have the weird lines. Any suggestions would be appreciated.

Thanks!
