Table

• In table we present data in 2-Dimension data grid format.
• By default display all data, means flat data structure.
• Rows not fixed but columns are fixed.
• When you add new dimension you can add them as “Values” and it will appear as a new column in grid.

Matrix

• It support Multidimensional data grid format.
• Matrix automatically aggregate the data according to data behavior.
