This doesn't sound like it would be too hard to do at all, but I really
can't read your table: could you resend the table and the desired
intermediate and final steps but format them more legibly?

Something like:

A B
2 545
NA8 784
NULL 3
269 NULL

assuming that is where you are starting.

I'm not entirely sure what you expect to happen moving from one table to
another, because the numbers change which seems that you are hoping for more
than a short and fill missing values....(545 becomes 543? 264 becomes 265
and 268?)

Again, it shouldn't be hard, just provide a more legible request and you'll
be on your way.
