Understanding Tables, Rows and Columns
Learn how Power BI organizes data into tables, records and fields. Work with a realistic sales dataset and make decisions from the table itself.
Concept 1 of 8
Understand the Structure of a Table
A Power BI table organizes related information into rows and columns. First, identify how the table is structured.
Click each part of the structure and inspect what it represents.
Why Tables, Rows and Columns Matter in Power BI
Power BI reports are built from data. Before creating charts, filters or dashboards, an analyst needs to understand how that data is organized.
A table contains rows and columns. A row generally represents one record or observation, while a column represents a field or attribute such as Customer, Region, Product or Sales.
Understanding this structure helps analysts select appropriate fields for business questions. For example, comparing sales by region requires a categorical field such as Region and a numerical field such as Sales.
This foundation becomes particularly important when we move into Power Query, relationships, data modeling and visualizations in later Power BI lessons.
