Adobe Flex and spreadsheet behavior

[mike...@gmail.com]

Hi there,
I like Flex a lot. One question here. Can we use Flex/Flash to create
data grids which mimic spreadsheet behaviors.

For example, I have 1, 2, 3 in cells, then I hightlight the 3 cells,
and drag in the corner, I can get 1, 2, 3, 4, 5, in a row or a column.

Another example. When I have 1, 1, 1, I hightlight and drag, I get 1,
1, 1, 1, 1, 1.

Any idea?

Thanks,
-Mike
