I'm migrating a larger project towards django-tables2, and I'd like to reuse some snippets both for tables and for other locations. TemplateColumn fills that niche very nicely, but it's hard-coded to use record as context object name, which doesn't play well with existing templates.

There are several ways this could be solved with fairly minimal impact:

• allow to set context_object_name like in other Django places, defaulting to record
• allow extra_context to be a callable, passing the arguments received by render()
• move context collection to a get_context_data method allowing for easy subclassing
