ColumnTemplate

AMD: require(["esri/widgets/FeatureTable/support/ColumnTemplate"], (ColumnTemplate) => { /* code goes here */ });
ESM: import ColumnTemplate from "@arcgis/core/widgets/FeatureTable/support/ColumnTemplate.js";
Class: esri/widgets/FeatureTable/support/ColumnTemplate
Inheritance: ColumnTemplate ColumnTemplateBase Accessor
Since: ArcGIS Maps SDK for JavaScript 4.24

A ColumnTemplate formats and defines the structure of a Column within a FeatureTable widget.

The FieldColumnTemplate is set directly on the table's template or its view model. The FeatureTable's tableTemplate contains a collection of column, field and/or group templates.

Property Details

declaredClass

Inherited
Property
declaredClass Stringreadonly
Inherited from Accessor

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

direction

Inherited
Property
direction String|null
Inherited from ColumnTemplateBase

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 fieldColumn in the same FeatureTable, it will only be honored on the column with the highest index. For example, let's say the first column called ObjectId is set to asc and another column later in the table order also has a set direction, the initial ObjectId column's direction will be ignored for the last one with the set direction.

Use this in combination with the FieldColumnTemplate.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:

  1. 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.
  2. Template - The editable permissions on a field can be configured by setting the editable property of the FieldColumnTemplate.
  3. 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.

initialSortPriority

Inherited
Property
initialSortPriority Number
Inherited from ColumnTemplateBase

Use this in combination with FeatureTable.multiSortEnabled and FeatureTable.direction properties to set sorting functionality on multiple columns. This property indicates the index of the sorted column when compared to other columns, with lower numbers taking a higher priority.

If no sort priority is set, the priority defaults to the most recently-sorted column. This occurs when sorting via the UI, or programmatically by calling FeatureTable.sortColumn. For example, using the example snippet below, the sort order priority is set for three columns, with "Status" having the least priority. Calling table.sortColumn("Status", "asc") would update the Status column to the highest priority. This would also occur if manually sorting via the column's UI.

Example
const table = new FeatureTable({
  layer: featureLayer,
  multiSortEnabled: true,
  tableTemplate: { // autocastable to TableTemplate
    columnTemplates: [{ // autocastable to FieldColumnTemplate
      fieldName: "ObjectId",
      direction: "asc",
      initialSortPriority: 1, // This field's sort order takes second-highest priority.
    },
    {
      fieldName: "Name",
      direction: "asc",
      initialSortPriority: 0, // This field's sort order takes the highest priority.
    },
    {
      fieldName: "Status",
      direction: "asc",
      initialSortPriority: 2 // This field's sort order is prioritized after Name and ObjectId, respectively.
    }]
  }
  container: "tableDiv"
});

addHandles

Inherited
Method
addHandles(handleOrHandles, groupKey)
Inherited from Accessor
Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 4.25.

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Manually manage handles
const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

this.addHandles(handle);

// Destroy the object
this.destroy();
Parameters
handleOrHandles WatchHandle|WatchHandle[]

Handles marked for removal once the object is destroyed.

groupKey *
optional

Key identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.

fromJSON

Method
fromJSON(json){*}static

Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.
