FieldColumn | API Reference | ArcGIS Maps SDK for JavaScript 4.30

The FieldColumn class works with the FeatureTable and provides the underlying logic for column behavior.

This class should be used for observing potential changes. Any configuration and changes to the field columns should be done handled via the TableTemplate and the FieldColumnTemplate class.

Property Details

alias Property alias Stringreadonly

The display name for the field.

autoWidth Inherited Property autoWidth Boolean Inherited from Column

Indicates if the column width will automatically adjust to account for large content. The column ignores the current width property when autoWidth is true.

Default Value:false

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

The name of the class. The declared class name is formatted as esri.folder.className.

defaultValue Property defaultValue Number |String |null |undefinedreadonly

The default value set for the field.

description Property description Stringreadonly

Contains information describing the purpose of each field.

direction Inherited Property direction String |null Inherited from Column

Controls the sort order of the column. This property will only be honored on one column in the FeatureTable widget. If direction is specified on more than one column in the same FeatureTable, it will only be honored on the column with the highest index.

This is used in combination with the initialSortPriority and FeatureTable.multiSortEnabled properties to set sorting functionality for multiple columns.

Possible Value	Description
asc	Sorts the column in ascending order.
desc	Sorts the column in descending order.
null	No sort is applied to the column.

Possible Values:"asc" |"desc"

editable Property editable Boolean

Indicates whether the field is editable. Editing permissions can be broken down with the following levels of priority:

Field - This is derived from the FeatureLayer or SceneLayer. It takes what is set in the Field.editable property. This must always be true for editing to be enabled. This can be overridden using a field column template.
Template - The editable permissions on a field can be configured by setting the editable property of the FieldColumnTemplate.
FeatureTable - The editingEnabled property must be set on the table in order for any type of editing to be enabled.

For example, if table editing is disabled in the widget, i.e. enableEditing is not set, it is still possible to enable editing for a specific column by setting the editable property. Vice versa is also true, if table editing is enabled, a field template can be used to disable editing for a specific column.

Ultimately, if the service's field is not editable, it is not possible to override its permissions using one of the options above.

FieldColumnTemplate.editable

effectiveLabel Inherited Property effectiveLabel String Inherited from Column

The sanitized label string safe for display in the header cell. Defaults to using fieldName if a label is not defined on the column.

field Property field Field

The Field associated with this column.

fieldName Inherited Property fieldName Stringreadonly Inherited from Column

The unique field name as defined by the data source.

flexGrow Inherited Property flexGrow Number Inherited from Column

Controls the flex-grow property for the column. When set to 0, cell width is fixed.

Default Value:1

formatFunction Property formatFunction FieldValueFormatFunction

Custom function for rendering cell content that is called when the column is rendered in the table. The function should return the formatted content to display within a table's cell. This can be a string, number, an HTML element, or equivalent node type (e.g. a Calcite component). If the content is an HTML element, it is appended to the root element. If the content is a string or number, it is set as the innerHTML of the root element. If the content is null, the root element is cleared. If the content is undefined, the root element is not modified. This property is useful when you want to customize the cell content. For example, you can use this property to create a custom cell renderer that displays a progress bar in the cell. The progress bar can be used to show the progress of a task.

frozen Inherited Property frozen Booleanreadonly Inherited from Column

Indicates if the the column is frozen in place at the beginning of the table. Column must be first in the FeatureTable's column's, or next to other frozen columns.

Default Value:false

Indicates whether a value is required when editing feature attributes within the table's cell.

resizable Inherited Property resizable Booleanreadonly Inherited from Column

Default Value:true

template Property template FieldColumnTemplate Since: ArcGIS Maps SDK for JavaScript 4.28 FieldColumn since 4.16, template added at 4.28.

A configurable template for the table column. The template allows for customizing the appearance of the column. Once the template is set, it will override the default appearance and will remain as such once the table is created. Any information regarding the column's current state can be accessed using the Column class.

Templates should be used primarily for initial column configuration and should not be used for observing changes.

textAlign Inherited Property textAlign String Inherited from Column

Aligns the columns cell content horizontally.

Possible Values:"start" |"center" |"end"

Default Value:"start"

textWrap Inherited Property textWrap Boolean Inherited from Column

Indicates cell content should be wrapped and displayed on multiple lines within the cell. Warning: this causes rows to expand when tall content is visible in the viewport. Scrolling tall cells into the viewport may cause the table to visually jump depending on the height of the expanding rows.

Default Value:false

timeZone Inherited Property timeZone Stringreadonly Inherited from Column

The storage IANA time zone of the column.

See also

visibleElements Inherited Property visibleElements VisibleElements Inherited from Column

The visible elements of the column's associated FeatureTable.

width Inherited Property width Number |String Inherited from Column

Width of the column in pixels. If providing value as a string, the string must include "px" suffix. This value is only honored when there are enough columns to fill the viewport, or flexGrow has been set to 0.

Default Value:200
