Applying CSS to Columns Collapsed by Responsive Extension

When Columns are collapsed by the Collapsed mode of the Responsive extension, the CSS that should apply to them (Namely Highlights in this table) fails to apply. Is there a way to get that css to apply properly?

Additionally, I am looking to force the first three columns of the Table into the collapsed section if possible. I have reviewed your suggestion Here (https://wordpress.org/support/topic/one-main-column-with-all-other-columns-in-collapse-mode/) but unfortunately, the datatables-row-details extension doesn’t work for me due to the face that the formatting still requires Left/Right Scrolling on Mobile and there is a complete removal of Responsiveness in the table. responsive=collapse and datatables_row_details=true does not seem to play nice.

Thanks for any help you might be able to offer!
