Tables and Matrices in Power BI

Updated: Nov 6

When using Power BI, many users want to increase efficiency for data management. Power BI has the advantage because the features accessible are high-level and can help users and organizations exceed analysis goals. Matrices and tables in Microsoft’s Power BI reach maximum ease-of-use and offer users tricks that competitors may have overlooked.


Using Power BI, you might want to make a table for data analysis. Tablix data regions are tables, and Power BI uses them to maximize data analysis. The tablix data region is a grid that is flexible that yields data in cells; tables have data shown in columns and rows. Users can choose to change the table and have features of other regions as the report is developed. Complex data and relationships are shown with nested tables, matrices, gauges, and charts, to name a few: tables have a tabular layout. Built on one data source, tables include row groups.

Data can be grouped with a single field, multiple fields, or create your own expression. Adjacent groups can show aggregated values for data, or add totals to groups: to increase ease-of-use for display, data can be emphasized – cells can be merged and formatting can be shown for data and headings.


Matrices differ from tables in what matrices show. With matrices, like a PivotTable or crosstab, rows and columns are for data summaries. Rows and columns for groups is determined by unique values, and you can group data by expressions – row and column groups yield matrices as column cells are added. Matrix cells group single data into one, (as the picture shows.) In addition, matrices display adjacent (peer relationship) and nested groups (parent-child relationship.)

Subtotals can be added for columns and rows; as mentioned in the accessibility blog, Power BI sports features that increase accessibility and ease for users, and matrices are no different. Merge, split, and format data for increased matrix possibility, and use drilldown toggles for revealing/hiding data. For more information on matrices and tables in Power BI, check out their site.
