(tables) Populate Column Using ManyToManyField

[mat]

Hi,
I'd like to populate a column using data from a ManyToManyField

Simple Example - A book with many authors:

class Book(models.Model):
authors = models.ManyToManyFields(Author)

class Author(models.Model):
name = models.CharField(max_length=200)

class BookTable(tables.ModelTable):
authors = tables.Column(data=?????)
class Meta:
model=Book

Any help would be appreciated.
