Table items are, essentially, nonspatial feature layers. They do not include a shape or geometry field and are not drawn on a map. They can be their own item or they can be a sublayer of a hosted feature layer.
Similar to a feature layer, each row in the table represents a single entity or occurrence and each field stores information that is an attribute of the entity or occurrence. For example, fields in a table that stores information about customers could have fields to store the account ID, contact name, contact phone number, and business name. Each row in the table represents a single contact.
Table items can contain text or numeric fields that represent locations, such as x,y coordinates or an address, but they are informational attributes and are not used to render the information on a map.
Settings on hosted tables
Hosted tables have nearly all the same settings as hosted feature layers. Only the settings related to the spatial column are not supported.
To learn how to manage settings for hosted tables, see Manage hosted feature layers and Manage hosted feature layer editing.
Creating a hosted table
You can create a hosted table item in ArcGIS Online when you publish from a comma-separated values (CSV) file or publish from a Microsoft Excel file and choose the None option under Location settings when publishing.
You can also publish from a stand-alone table in ArcGIS Pro.
Using hosted tables
In Map Viewer, you can add table items from the Table tab of the Contents (dark) toolbar. When added to Map Viewer, the table opens automatically. See Show tables for more information.
You can edit the values in a table in Map Viewer, or open the Data tab of the table's item page to edit attribute values. As with hosted feature layers, the item owner and organization administrators can always edit. For all others, editing must be enabled on the table and you must be a member of a role that has the privilege to edit features.
If the table owner or an organization administrator enabled attachments for the table, you can also attach relevant files to rows in the table.
Tables can be joined to feature layers by creating a joined hosted feature layer view to provide additional attributes for the same features. If you publish a feature class and table related through a geodatabase relationship class from ArcGIS Pro, the resultant hosted feature layer will contain a feature layer and related table.
