In order to create an infographic in Pages, you'll need to customize the size of the page in Page Setup under File. Change the Paper Size to your own customizable size for your infographic. You can always go back in and make the page longer. So you'll be creating a one page document in Pages - the page just happens to be a looooong page.

Adding Tables

Click on table in the menu bar. The Inspector automatically opens to the table formatting. While the table is still selected (you'll see the handles) click on more rows or more cells.
