Identify Row on Current Page

I have an external action that requires me to loop through all the rows in my table and inspect the data. However, I also want to manipulate the rows that are currently visible or displayed on the current page.
Is there a way to test the row to see if it is currently visible/on the current page?

    table.rows().every(function(idx, tLoop, rLoop){
        var data = this.data();
        // ... do something
        if (this.isOnCurrentPage()) {
            // ... do somehting more
        }
    });

isOnCurrentPage() is just an example of what I'm trying to do. I don't know if I could use a selector some how or something of the like.

Any ideas?
Thanks
