What is a key feature of filtering expressions in a composite worksheet?

A key feature of filtering expressions in a composite worksheet is their ability to apply multiple filtering levels, which significantly enhances data analysis. This capability allows users to refine and narrow down their data sets by applying various criteria simultaneously, thereby facilitating a more detailed investigation into the data.

By utilizing multiple levels of filters, users can drill down into specific subsets of data that meet certain conditions or characteristics, making it easier to derive insights and identify trends or anomalies. This multi-faceted approach to filtering is particularly important in complex data environments where simple, single-dimensional filters might not adequately address the analytical requirements.

This functionality of filtering expressions thus provides a powerful tool for users to dynamically interact with their data and tailor the view to suit specific analytical needs.
