Spreadsheet Aggregation Rows vs. Aggregation Columns

An aggregation cell is often defined as an aggregation function (e.g. SUM, AVG, MAX, MIN and etc) over a group of other cells.
We say a row is an aggregation row if the cells of the row are aggregation cells.
Similarly we say a column is an aggregation column if the cells of the column are aggregation cells.
For example, the two figures below show the aggregation rows and aggregation columns in a spreadsheet.
