No wrap/No wrap exempt columns

Hi,

I’m trying to have one column on my table not wrap (all could have this command, but one column should not). I’m trying to do this without inputting a specific width px or % (these CSS codes do not seem to be working for me).

I’ve combed through the forum and I found this past question:
https://wordpress.org/support/topic/nowrap-in-colums?replies=8

I used the 2 codes (in the replies), but made them fit according to my table. The only thing that worked was the nowrap command, but the column (column 8) that I want to wrap will not wrap with this Custom CSS.

Has the code changed or been updated? Help is appreciated.

Here’s the table:

Here’s the entire custom CSS:

.tablepress td,
.tablepress th {
	padding: 8px;
	border: none;
	background: 0 0;
	text-align: left;
	font-size: 90%;
	line-height: 120%;
	float: none !important;
}

.dataTables_filter {
	float: left;
	white-space: nowrap;
	margin-bottom: 15px;
}

.tablepress-id-8 th,
.tablepress-id-8 td {
	white-space: nowrap;
}

.tablepress-id-8 .column-8 {
	white-space: normal;
}

FYI: Table 8 is my test table.
