You can set up some fields that track the starting and ending row to
display. Ending row can be calculated by the starting row + some page length
(i.e start = 4, count = 4, end = (start+count = 8))

Then in your repeating table, you can use filters (for main data source
tables) or conditional formatting (for secondary data source tables) to
limit the rows shown based on the start and end values.
