The main difference between a matrix and a table in Power BI is as follows: • Table: • A table visual in Power BI represents data in 2-Dimensional format.   • It supports flat data where data is displayed in rows and columns, including duplicate values with no implicit aggregation or hierarchical grouping. • Tables are useful for displaying detailed, individual records. • Matrix: • A Power BI matrix visual represents data in multiple dimensions format. • It supports a stepped layout where data is displayed in rows and columns, but it allows for hierarchical grouping, aggregation, and drill down functionality. • It provides subtotals and totals for grouped data, making it suitable for summarizing and analyzing data across multiple dimensions.
