how to use formula in a table

In order to perform a calculation on input table, you can use the update/calculate field conditional logic or form calculation widget.

I have prepared an example form that includes input table with calculate field conditional logic:

the condition for the first row (d1=a1+b1+c1):

the condition for the second row (d1=(a1+b1)-c1):

Also, I kindly recommend you to check these guides below in order to learn more about form calculation :
