Top table border appears where there should be none

When I create a table, tried various sizes with various contents, and set borders to 0, I still get a top border line. How do I get rid of it? I've tried everything, but with no luck. Even when moving the image to the top of the page, can still see the top border line. And if moved down the page, the border line is obvious. See the attached image and notice the thin line above the graphic and text.

Any help would be greatly appreciated!
Thank you,
