This question is best explained by giving the usecase:
I have a table where I list some data and I would like to add a column to the right which gives the ratio of two adjacent rows. Now to make it more obvious the ratio of which rows this is I would like to shift the column which the ratios by half the height of a row so that each of the ratio values sits to the right of the two columns which it was calculated from.
E.g. instead of this
A ratio ------------ 3 2 6 3 18
imagine the same table but the numbers in the right column shifted down by half a row.
Is this even possible?
