Have you tried this, CR viewer properties -- BestFitPage ( by default it's value set to true, now make it false and set the width of viewer) . Sometimes viewer width disturbs UI of that webpage.
One more thing to note,
you might have placed CR viewer under div and table tags. once remove all these and place just viewer on the same page to check out.
