Abstract: A method and associated systems for representing multidimensionality of a data table by combining a first set of data elements, units, or cells of the table into a multidimensional, expandable, second data unit. One or more processors of a computer system: determine a set of a first data units to be combined; determine a type of multidimensionality of the second data unit after combination; and combine, as a function of the type of multidimensionality, the first set of the first data units into the second data unit. The type of multidimensionality may be horizontal, vertical, or higher-dimensional (that is, greater than two-dimensional) dimensionality.
