column name

The name given to a column. In the follow example, the column name is age.

class SimpleTable(tables.Table):
    age = tables.Column()
empty value
An empty value is synonymous with “no value”. Columns have an empty_values attribute that contains values that are considered empty. It’s a way to declare which values from the database correspond to null/blank/missing etc.
order by alias

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.
