I am looking to create a grid layout with 3 rows, followed by a bold line to separate the 3rd row from the 4th row. Then I want another 3 rows, with another bold line separating the 6th row from the 7th row, and so on.
Any suggestions on how to achieve this layout?
For example:
Row 1
Row 2
Row 3
-------------
Row 4
Row 5
Row 6
-------------
