What element of a pivot table is used to categorize source data within a column?

In a pivot table, the element that is used to categorize source data within a column is the Rows. Rows in a pivot table represent categories or groups that the data can be organized by, allowing users to analyze trends, comparisons, and patterns across different segments of their data. When data is arranged in rows, it makes it easy to summarize and visualize the information, as each row represents a different category while the data can be aggregated in various ways.

This structure is crucial for interpreting the data effectively, as it provides a clear framework for organizing information and helps in reporting or analyzing specific aspects of the dataset.
