Computed Column

Note the following differences between computed columns vs. computed cells:
Computed ColumnComputed Cell
A single function reference in the calculator column property is used to compute the values for all the cells in the column. Each computed cell has a calculator function in place of its value. The grid displays the value returned by the calculator.
There can also be a cell value, which the calculator can reference and operate on in addition to the other columns' value and any other variables in it's closure. The cell value is a reference to a calculator function. There is no cell value per se; the calculator therefore can only operate on the values of the other columns' values and other variables in it's closure.
