A non-field based LinkColumn always renders long dash

[singalen]

I see a pretty erratic behavior in BoundRow.__getitem__. It doesn't account for a LinkColumn that is not based on a field, which is pretty normal thing.
My field was declared as

delete_link = tables.LinkColumn(
    'order_delete',
    kwargs={'customer_pk': tables.A('customer.id'), 'pk': tables.A('id')}
)

and due to mentioned method was always rendered as an empty value.

Adding

    accessor=tables.A('id'),

helped, but it's clearly a workaround. The column doesn't have to be data-based at all.

Or this should be a part of documentation: http://stackoverflow.com/a/24346861/207791. But better fix the logic.

I agree this is not a well defined API. Any idea's how to make it nicer?

For the sake of the least surprise, I would just fix BoundRow.__getitem__ to account for None in bound_column.accessor, and supply no or empty value as available['value'].

@singalen sounds good, care to provide a patch?
