Column¶

Base class: Part

Class that describes a column, i.e. the text of the header, how to get and display the data in the cell, etc.

See Table for more complete examples.

Parameters with the prefix filter__ will be passed along downstream to the Filter instance if applicable. This can be used to tweak the filtering of a column.

Refinable members¶

`after` (evaluated)¶

Set the order of columns, see the howto on ordering for an example.

Type: Union[int, str]

See after

Cookbook:: How do I reorder columns?

`assets`¶

Type: Namespace

See assets

What attribute to use, defaults to same as name. Follows django conventions to access properties of properties, so foo__bar is equivalent to the python code foo.bar. This parameter is based on the name of the Column if you use the declarative style of creating tables.

Type: str

See attr

Cookbook:

`auto_rowspan` (evaluated)¶

enable automatic rowspan for this column. To join two cells with rowspan, just set this auto_rowspan to True and make those two cells output the same text and we’ll handle the rest.

Type: bool

Default: False

Cookbook:: How do I get rowspan on a table?

`bulk`¶

Namespace to configure bulk actions. See howto on bulk editing for an example and more information.

Type: Namespace

Cookbook:: How do I enable bulk editing?

`cell`¶

Customize the cell, see howto on rendering and howto on links

Type: Namespace

Cookbook:

How do I show row numbers?

How do I show nested foreign key relationships?

How do I create a column based on computed data (i.e. a column not based on an attribute of the row)?

`choices` (evaluated)¶

Type: Iterable

`data_retrieval_method` (evaluated)¶

Default: DataRetrievalMethods.attribute_access

`display_name`¶

the text of the header for this column. By default this is based on the _name so normally you won’t need to specify it.

See name

Cookbook:: How do I specify the title of a header?

`endpoints`¶

Type: Namespace

See endpoints

`extra`¶

Type: Dict[str, Any]

See extra

`extra_evaluated`¶

Type: Dict[str, Any]

See extra

`extra_params`¶

See extra_params

`filter`¶

Type: Namespace

Cookbook:

How do I enable searching/filter on columns?

How do I make a freetext search field?

`group` (evaluated)¶

string describing the group of the header. If this parameter is used the header of the table now has two rows. Consecutive identical groups on the first level of the header are joined in a nice way.

Type: Optional[str]

Cookbook:: How do I group columns?

`header` (evaluated)¶

Type: Namespace

Cookbook:: How do I customize the rendering of a header?

`include` (evaluated)¶

set this to False to hide the column

Type: bool

See include

Cookbook:

How do I show a reverse many-to-many relationship?

How do I show a reverse foreign key relationship?

`iommi_style`¶

Type: str

See iommi_style

`model` (evaluated)¶

Type: Type[Model]

`model_field`¶

`model_field_name`¶

`render_column` (evaluated)¶

If set to False the column won’t be rendered in the table, but still be available in table.columns. This can be useful if you want some other feature from a column like filtering.

Type: bool

Default: True

Cookbook:: How do I specify which columns to show?

`row_group` (evaluated)¶

Type: Namespace

Cookbook:: How do I group rows?

`sort_default_desc` (evaluated)¶

Set to True to make table sort link to sort descending first.

Type: bool

Default: False

Cookbook:: How do I set the default sort direction of a column to be descending instead of ascending?

`sort_key`¶

string denoting what value to use as sort key when this column is selected for sorting. (Or callable when rendering a table from list.)

`sortable` (evaluated)¶

set this to False to disable sorting on this column

Type: bool

Default: iommi.table.default_sortable

Cookbook:: How do I turn off sorting? (on a column or table wide)

`superheader` (evaluated)¶

    # rows will either be a queryset, or a list of elements
