Is there a single command that will fill each blank cell below a cell
with a number with that same number? There are 435 numbers and
different numbers of blank cells (including none) below each number.
A portion of the table is shown below. I want, e.g., the cell below 1
to show 1, the two cells below 2 to show 2, the two cells below 3 to
show 3 - and because there is no blank below four, move on to the next
1, etc.
