Cells can hold the result and is stepwise by nature.
The intermediate result can be referenced by row and column numbers. This is much simpler than the traditional scripts.
Stepwise computation is not supported in SQL, and thus the computation complexity is increased
In the expression A1.select(Gender==”Male”) of cell A2, you can use A1 to directly reference the result of previous step. In the expression A2^A3 of cell A4, the A2 and A3 is directly referenced with the cell name.
