Feature
A table of features that typically represent real-world objects such as fire hydrants, roads, and forests. This is the base class for a number of different feature tables, such as ServiceFeatureTable, FeatureCollectionTable, and GeoPackageFeatureTable.
The records in a feature table must all have geometry (shape and location) or have no geometry (just attribute values). If the records have geometry (FeatureTable.hasGeometry is true), you can display the features by creating a FeatureLayer from the feature table and adding the feature layer to the ArcGISMap or ArcGISScene's collection of operational layers (GeoModel.operationalLayers).
FeatureTable provides methods for spatial and attribute querying (for example, FeatureTable.queryFeatures(QueryParameters)), and methods to add, update, and delete features (such as FeatureTable.addFeature(Feature), FeatureTable.updateFeature(Feature), and FeatureTable.deleteFeature(Feature)).

Properties
A user-friendly name that can be displayed in the UI (for example, in a Table of Contents). If the table is displayed with a FeatureLayer, the FeatureTable.displayName is used as the FeatureLayer.name.
The type of geometry of the features stored in this table. If FeatureTable.hasGeometry is false, then the geometry type is GeometryType.Unknown.
True if the feature table supports geographic features, false otherwise.
True if this feature table is editable, false otherwise. Underlying file permissions (for subclasses such as ShapefileFeatureTable and GeodatabaseFeatureTable) can be changed while the feature table is open. In these cases the value of this property may not be accurate.
The layer that displays this table, if any. The Layer type depends on how the feature table is created. For example, a Layer will be an AnnotationLayer if the FeatureTable is created from a table that supports annotation. See Layer for more information about the supported layer types.
The number of features in the table. If all the features are stored in the local table, for example with a GeodatabaseFeatureTable or a ShapefileFeatureTable, then the FeatureTable.numberOfFeatures will return the full number of features.
The spatial reference of the table. A spatial reference defines how the coordinates of a feature's Geometry correspond to locations in the real world. For more information, see the SpatialReference class or the Spatial references[https://developers.arcgis.com/documentation/spatial-references/] documentation.
Inherited properties
A flag indicating whether the PopupDefinition defined on the PopupSource is enable / disable. Will return false if an error occurs.
The load status.
The pop-up definition. The PopupDefinition associated with the popup source. A null if an error occurs or if the popup source is not associated with a pop-up definition.
Functions
Adds a feature to the table. Adding a feature that contains a Geometry causes the geometry to become simplified. This may change a single part geometry to a multipart geometry, or round off X, Y, Z, and M coordinate values that are above the resolution set by the SpatialReference.
Adds a collection of features to the table.
Determines whether you can add new features to the table. Although this method may state that the table allows new features to be added, the application may not be licensed to permit this. For example, a user cannot add features to a secured feature table if the application is licensed at the Lite level (LicenseLevel.Lite).
Determines whether you can delete the feature from the table. Although this method may state that the table allows the feature to be deleted, the application may not be licensed to permit this. For example, a user cannot delete features from a secured feature table if the application is licensed at the Lite level (LicenseLevel.Lite).
Determines whether you can edit the geometry field in a table. Although this method may state that the table allows geometry fields to be edited, the application may not be licensed to permit this. For example, a user cannot update geometry in a secured feature table if the application is licensed at the Lite level (LicenseLevel.Lite).
Determines whether you can update the feature in the table. Although this method may state that the table allows the feature to be updated, the application may not be licensed to permit this. For example, a user cannot update features in a secured feature table if the application is licensed at the Lite level (LicenseLevel.Lite).
Creates a new empty feature. The new feature is only available in memory at this point. Execute FeatureTable.addFeature(Feature) to commit the new Feature to the table.
Creates a new feature with the provided attribute values and, optionally, geometry. The new feature is only available in memory at this point. Execute FeatureTable.addFeature(Feature) to commit the new Feature to the table.
Deletes a feature from the table. Deleting a feature from a GeodatabaseFeatureTable in a stand-alone mobile geodatabase created with ArcGIS Pro is not supported when the table participates in a controller dataset, such as a utility network or parcel fabric. Use FeatureTable.canDelete(Feature) to determine if this operation is allowed.
Deletes a collection of features from the table.
Determines the minimum bounding envelope that contains features satisfying the provided query parameters. If no features meet the query criteria, an empty envelope is returned.
Determines the count of features that satisfy the provided query parameters.
Submits a query against the table.
Calculates values for the requested statistics. Statistics query parameters may also define fields on which results are grouped or sorted.
Updates a feature in the table. If you update a feature that contains a Geometry, the geometry becomes simplified. This may change a single part geometry to a multipart geometry, or round X, Y, Z, and M coordinate values that are above the resolution set by the SpatialReference.
Updates a collection of features in the table.
