Which of the following is a common table for building worksheets?

The Activity table is commonly used for building worksheets because it serves as a foundational element in many planning and operational processes. This table organizes and tracks various activities within a project or plan, providing essential information such as resource allocation, timelines, and status updates. Using an Activity table allows users to clearly define tasks, responsibilities, and schedules, which is crucial for effective workflow management.

In contrast, the other tables mentioned have specific uses but don't serve as a common basis for worksheet development. The Sales projection table is focused on forecasting financial performance, the Image reference table is intended for visual data representation, and the User feedback table tracks customer insights. While these tables are useful in their respective contexts, they do not generally function as the foundational elements for building worksheets in the same way that the Activity table does.
