Table - space between specific rows

Hi Emma_ 

In Power BI, a value can’t be assigned to a row that doesn’t exist, even if the intended value is blank. That blank row has to exist first. One way to handle this is to add a dimension table that includes an explicit blank row, like in the example below. The category column also needs a custom sort; otherwise, the blank row will always appear first.

Use this dimension table in  the visual and ensure that Show items with no data is enabled

Please see the attached pbix.
