How to make cells shift up and to the right or down and to the left in a table in Word.

Question

I have a table with 2 columns and hundreds of rows. The cells contain pictures which a references for anohter document so the order of them is key. Table is like so

1 2

3 4

5 6

I want it so if I need to insert another cell they would move like so

1 2

7 3

4 5

6

And if I delete a cell it would do the following

1 2

4 5

6

Can't seem to find a solution myself or online. Can't imagine I'm the first person to have this problem.
