What were individuals who filled in values in tables referred to as?

In the context of working with data in tables, individuals who filled in values are typically referred to as "Calculators." This term emphasizes the role of these individuals in processing numerical or tabular data, as they are often tasked with performing calculations or entering specific values based on certain criteria or observations. The act of filling in tables often involves detailed attention to quantities and accuracy, which aligns with the concept of calculation.

The other roles such as Analysts, Engineers, and Programmers refer to broader or different responsibilities that involve data interpretation, system design, and software development respectively, rather than the specific task of populating values in a table format. Analysts focus more on understanding and interpreting data for decision-making, Engineers are generally involved in designing systems or products, and Programmers write code to create software solutions. Therefore, the specific act of entering values as described best fits the term "Calculators."
