Many WordPress themes have built in shortcodes for creating column widths within page and post content. What do you do if you want to include these handy shortcodes within a theme that does not have this feature? You basically have two options either create your own custom code or use an existing plugin like WP Easy Columns.
We have been using Easy Columns and it is a pretty good plugin. The shortcodes are a little long for my liking but using the interface offered in the editor makes it fairly simply. Training a client on how to use these should not be a challenge. It is certainly a quicker method than creating this from scratch or following a tutorial and has some advantages.
