Table settings allow you to change global table configuration in one place.
To enter table settings, click on the gear icon.
In the upper part, you can edit the table name, description, icon or color.
You can also add and remove attributes (columns) from the table, or set which attribute is marked as a displayed attribute. It should be the main attribute which describes the row, e.g. in Tasks table it is task name.
You can also edit rules, link types and users here. Read more about those topics in separate articles:
