Remove empty rows based on a cell range.

Is there a way to remove empty rows, by selecting a specific range of rows only.
In the attached sheet, the range is Rows $A$20 to $A$45 inclusive, but it must start at row 20.
If the code can be limited to the range stipulated only, if empty they will remove the row, stopping at row 46 - which contains data.

So it checks the row, if populated move to the next row, if populated move to the next row, and so on until it finds an empty cell in column A, then deletes the row and continues down until the last empty row in the range inclusive of $A$45.
