Auto-populating checkbox filters

dgrub

Is there a tool or extension that can identify all possible field values for a column and create checkbox filters for them?

As an example, in the colvis demo: http://datatables.net/extensions/colvis/
What I would like for this is a set of checkboxes including accountant, junior technical author, software engineer, etc.

Also:
If in the Colvis demo, the city field was actually a list of cities, is there a way of doing the same checkbox? EG if each person had an 'offices' field which may include ['tokyo', 'london'], ['san francisco'], ['tokyo', 'san francisco']

Thanks for your help.
