Data Table refresh

On the attached ss, the two blue tables are linked to an Access Database and are refreshed via the button.

As you can see they cover rows 20-40

On refresh, some rows will be lost making the range more like 20-36

The data in A1:I16 is reading these data tables, so unless the data tables always have 20 rows, i get ref errors.

How can i essentially lock those data tables so they will always show 20 rows and if there is no data, they are just blank

Thanks!
