The name given to a column. In the follow example, the column name is age.
class SimpleTable(tables.Table):
age = tables.Column()
A prefixed column name that describes how a column should impact the order of data within the table. This allows the implementation of how a column affects ordering to be abstracted, which is useful (e.g. in querystrings).
class ExampleTable(tables.Table):
name = tables.Column(order_by=('first_name', 'last_name'))
In this example -name and name are valid order by aliases. In a querystring you might then have ?order=-name.
