Hi,
I'm trying to implement something similar to Excell's "Freeze Panes" functionality.
I would like to have a table when only the cells scroll and the headings stay on top.
See the attached code for an example. I would like the '0' and '1' headings to stay on top.
A possible solution is to put two frames one on top of the other, when only the lower is scrollable. This works but you loose the strength of the "grid" geometry manager, and you need to take care of the sizes so the columns align all right.
Thanks!
