What should be indicated in the columns if you do not want to include key fields in the worksheet?

To not include key fields in a worksheet, indicating default values for columns is an effective approach. Default values allow users to understand the structure of the data without needing to focus on specific key fields that may not be relevant for their current task. By providing default values, it creates a clear understanding of what data can be expected while simultaneously removing the emphasis on those fields that are not necessary for the immediate context or analysis.

This method maintains the integrity of the data model but allows for flexibility in user interaction without overwhelming them with key identifiers that may not be essential to their work. It promotes a streamlined approach to data entry and analysis, enabling users to concentrate on the data that is most pertinent to their needs.
