I am not sure if you would like to display in the center column just a different content for each clicked link or you would like to dosplay the whole page in the center content. Anyway you have to create a different page for each link you have in the left column. Than you share the link feature between all created pages (using the "publish" functionality). Then - depending wheather you want to display just a different content or the whole page in the center content you should either just fill the content for each created page or (in case you want to display the whole page) use the iframe feature.
