At the top of the column in the down arrow menu, you can set to math input.
For tables, you have to code cell by cell. You can potentially import a column into a graph list using the graph CL. You can always hide graphs if you don’t want them visible, but want to perform calculations.
numberList(`L`): table8.columnNumericValues(2)
Then, within the graph you can perform calculations. Like make a list that is your key, and then a list to give points or whatever for corrections. C_heck below is checking if the difference of corresponding elements is zero. If so, it outputs 1 otherwise 0:
K_ey=[16,12,8,7]
C_heck={|K_ey-L|=0:1,0}
S_core=total(C_heck)
