Hi,
How do you send a list of elements from a table, including blank cells,
to an elisp function?
I have the table below with points on exam questions in columns 2-4. The
second row contains the maximum number of points for each question. The
student rows contain the actual points received. I want to compute the
maximum possible sum for a student, to be updated while I grade the
questions.
I have written an elisp function that takes two lists as arguments and
does the necessary computations. However, the standard selection
argument ignores blank elements. In the function call below, the
function will receive the (fontified) lists '("3" "4") '("6" "4" "6")
and '("6" "2") '("6" "4" "6"), respectively. I need a selection where
each blank element is kept as, e.g., fontified "". Thus, I would like
the function to receive '("3" "4" "") '("6" "4" "6"), etc.
Is that possible?
Have tried google and the org manual to no avail.
