dojo.require("esri.dijit.FeatureTable");
Description
(Added at v3.12)
Creates an instance of the FeatureTable widget within the provided DOM node. The FeatureTable is a widget-based solution for where you explore and optionally edit the attribute data of a feature layer. The FeatureTable also integrates any additional information such as related records and attachments.
Feature attributes displayed in the table can be edited by setting FeatureTable's editable property to true
. However, setting this property to true
does not make the layer editable if the editing capability for the service is set to false
on the server.
The pieces of related information can be exposed as columns directly in the table by setting FeatureTable's showRelatedRecords property to true
. The attachments can also be displayed in the table by setting its showAttachments property to true
. To help distinguish the related records and attachments from the fields in the table, the related records and attachment columns are appended to the end of the table, with the column names shown in italics. Each record in the table shows the number of related records and attachments associated with it.
As a developer you have the option to select or filter features in the table. If you call FeatureTable's selectRows() method, the selected records will be highlighted in the table while all other records remain visible. When FeatureTable's clearSelection() method is called, the selection/highlights will be removed from the table. If you call FeatureTable's filterRecordsByIds() or filterSelectedRecords() the table will only display those records that were filtered. FeatureTable's clearFilter() method will remove the filter as well as the selection/highlight from the table.
At 3.18, editing is allowed on any field in the table. This includes fields that define the relationships. However, if you edit a field that has a defined relationship, the table does not immediately update the related records. You will need to refresh the page to see the updated related records.
At 3.27, the table will automatically refresh if a feature layer has a refreshInterval set.

However, it won't enable selection of records in the table when user clicks on a feature on the map. To enable selection from the map to the table, the developer must explicitly implement the layer's click logic. This is because the application might have its own selection logic elsewhere or their own click logic. (Added at v3.16)
Default value: false
