In designing interfaces for dynamic operation, I am finding that I cannot figure out how to get alignment to work. For example:
Row[{Panel[Column[{1, 2, 3}]],
Panel[Column[{4, 5}]],
Panel[Column[{6, 7, 8, 9, 10}]]},
Alignment -> {Top, Center}]
How do I get the panels to align to the top of the row?
