In which Ribbon Tab would you find the option to add a Total Row in a table?

To add a Total Row in a table, you would navigate to the Design Ribbon Tab. This tab includes features specific to table formatting and functionality, including options for adding a Total Row, which allows you to perform calculations on the data in your table, such as summing or averaging values in a column.

These functionalities are designed to enhance the usability of tables, making it easier for users to summarize data at a glance. The Design Ribbon Tab focuses on the visual and functional enhancements of tables, which is why it contains the option for the Total Row.

Other Ribbon Tabs do not focus specifically on table functionalities. The Data Ribbon Tab is primarily used for data manipulation and analysis tools, while the Layout Ribbon Tab typically addresses the arrangement of objects and text, and the Review Ribbon Tab deals with comment features, spelling, and tracking changes. Thus, none provide the specific table-related features found in the Design Ribbon Tab.
