The operations that can be performed in the "Data Table" view are editing, adding, deleting fields, deleting records, and data search, etc. However, the table structure established using the "Data Table" view only describes the table. The field name does not indicate the data type and attribute value of each field, and it cannot be modified.

What operations can be performed in Datasheet view

In the datasheet view, the operations that can be performed are: 1. Delete a record; 2. Delete a field; 3. Modify the name of the field.

In datasheet view, the operation that cannot be performed is to modify the field type.

In the "Data Table" view, you can edit, add, delete fields, delete records, and search for data. However, the table structure established using the "Data Table" view only describes the fields in the table. name, but does not specify the data type and attribute value of each field, and cannot be modified.

Related introduction:

A view is a virtual table derived from one or several basic tables (or views). Only the definition of the view is stored in the system's data dictionary, and the data corresponding to the view is not stored.

A view is a transformation of the original database data and another way to view the data in the table. You can think of a view as a moving window through which you can see the data of interest. Views are obtained from one or more actual tables whose data is stored in the database. The tables used to generate a view are called the base tables of the view. A view can also be generated from another view.

The definition of the view exists in the database, and the data related to this definition is not stored in the database. The data seen through the view is stored in the base table.

The view looks very much like a physical table in the database, and its operations are the same as any other table. When you modify data through a view, you are actually changing the data in the base table; conversely, changes in the base table data will automatically be reflected in the views generated by the base table. For logical reasons, some views can modify the corresponding base table, while others cannot (only query).
