Columns
The last section «Columns» allows you to configure the parameters of the export columns, both the name and the calculation.
In each field of the export you will see the section «Column Name» where you can change the name of the column if you wish. Otherwise, the one that already appears in the field will be left by default.
You will also find the «Calculation» section that will let you choose, by means of a drop-down, the type of calculation that all the data in that column will do (Without calculation, Maximum, Minimum, Average, Add and Count). Remember that calculation can only be chosen if the field referred to in the column deals with numeric data.
