Handy little function. And opposed to calc, it writes the result into the buffer. Would be nice if it supported floats too. Also, I’m afraid it doesn’t work when there aren’t enough blank lines before the end of the buffer. Unless next-line-add-newlines is non-nil, I guess (haven’t tried).

or just use C-x * : (calc-grab-sum-down): “Parse a rectangle as a matrix of numbers and sum its columns.”
