You need to use a 'renderer' to generate your column data. This allows you to render out HTML (or anything else) as you column data so you can build things like dropdowns and multiselects. If you use that and want to search by that column, you will probably also want to look at the 'filter_condition_callback'. This allows you to call a custom method when searching by a column.

This seems to be a reasonable, quick summary of the subject.
