Here’s a quick video (3 minutes) which shows how to format a Moodle page pretty easily by using a table. There are some drawbacks for accessibility, however it is a super easy way to improve the layout and usability of a site without too much programming knowledge (i.e. right through the html editor). The example showcases HTMLarea (the text editor from Moodle 1.9) but the table formatting options are available in any Moodle text editor version.
