How can I highlight only the contents that have been never published yet in the Views? The contents always need approval of administer to be published on this site.

For example,
The contents are once unpublished by Rule module when non-adimin users update them.
And then the administer publish those contents again.

I have a node View with table style.
In this view the administer wants to find "The contents that have never been published yet" easily for example, by making them hi-lighted.

Is there any way to achieve this?
To display unpublished  content using views you  have to add "Node: Published" option as "No" under "Filters".
