<a id="GRANTA_MIScriptingToolkit.granta.mi_attribute_classes.AttributeDefinitionTabular.columns"></a>

#### *property* columns

Column names (headers).

- **Returns:**List\[str\]

<a id="GRANTA_MIScriptingToolkit.granta.mi_attribute_classes.AttributeDefinitionTabular.columns_to_process"></a>

#### *property* columns\_to\_process

Columns to be included when populating an AttributeTabular object. Defaults to all columns, which will fully populate the AttributeTabular object. Columns that aren’t processed contain the value `<ignored>`. Tabular attributes with `<ignored>` columns can be imported back into Granta MI with no loss of data (additional conditions exist for Picture and File columns, see Warning below).

Ignoring columns that aren’t required by the script can significantly improve performance for operations with large amounts of tabular data.

#### NOTE

This property must be set on the AttributeDefinitionTabular object associated with the Table object *before* data export for the setting to have an effect.

#### WARNING

If the intention is to export, modify, and update tabular data, and [`Table.bulk_fetch()`](table.md#GRANTA_MIScriptingToolkit.granta.mi_tree_classes.Table.bulk_fetch) is being used for the initial export of data, it is recommended to call [`Table.bulk_fetch()`](table.md#GRANTA_MIScriptingToolkit.granta.mi_tree_classes.Table.bulk_fetch) with `include_binary_data = True`.

If [`Table.bulk_fetch()`](table.md#GRANTA_MIScriptingToolkit.granta.mi_tree_classes.Table.bulk_fetch) is called with `include_binary_data = False`, Picture and File columns **must not** be removed from the `columns_to_process` list or an exception will be raised when attempting to re-import the tabular attribute.

It is possible to call [`Table.bulk_fetch()`](table.md#GRANTA_MIScriptingToolkit.granta.mi_tree_classes.Table.bulk_fetch) with `include_binary_data = False` as long as all Picture and File columns are set to be processed, but this will have a performance impact. See the [`Table.bulk_fetch()`](table.md#GRANTA_MIScriptingToolkit.granta.mi_tree_classes.Table.bulk_fetch) documentation for more details.

- **Returns:**List\[str\]

<a id="GRANTA_MIScriptingToolkit.granta.mi_attribute_classes.AttributeDefinitionTabular.ignore_linked_records"></a>

#### *property* ignore\_linked\_records

Whether to ignore linked records when creating Record objects. Defaults to `False`. Even when set to `True`, linking values are still available if populated.

Ignoring linked records if they aren’t required can significantly improve performance for operations with large amounts of tabular data.

#### NOTE

This property must be set on the AttributeDefinitionTabular object associated with the Table object *before* data export for the setting to have an effect.

- **Returns:**bool
