Within IJ, tables can be a lot easier to get to behave themselves because they automatically have the capacity to line up side by side; divs have to be forced to float and cooperate, and it can take a lot more in-html code than it would in a regular page. But I'm so used to them now that tables don't work as well for me anymore. :/ I didn't get divs for the longest time either, and then my first web professor gave us a lecture about them that made it all make sense.
