AttachmentsColumn | API Reference | ArcGIS Maps SDK for JavaScript 4.30

The AttachmentsColumn class works with the FeatureTable to display attachment counts for each feature in the table. If a feature has attachments and the table is configured to enable Attachments, the count is displayed in the cell. Whereas the cell is empty if the feature does not have attachments. This column is always appended to the end of the table.

This class should be used for observing potential changes. It is designed primarily to read and not interact directly with the attachment columns.
