Line prefix formula
To avoid double calculations and formula copies, values in tables can be defined centrally in preformulas. In addition to the preformulas described above, row preformulas can be defined for calculations based on the row object.
In addition to the function of making values of global variables available, row preformulas also have the purpose of filtering out rows in the table using MM-Talk conditions. Row preformulas should return a value of the type "Boolean", "True" means that the row remains in the table.
Use global variables in line preformulas. Please also read the section Global variables.
