Clear and concise description of the problem

The current table only supports plain data organization, there are no logic/math functions like SUM, MEAN, etc. like the ones in Microsoft Excel.

Suggested solution

Introduce a special type of escape sequence only for cells in tables. For instance, by typing \SUM(A1, F1) in a cell, the cell automatically calculates and displays the value of the sum from A1, B1, …, to F1.
