about wxpython and grid, two problems snif ;)

[ricky]

hello

i need your help for two problemes :

1) is it possible to easily hide some row, and recover them ?

2) is it possible to have different colours on the label columns?
for instance, when a row is selected, having the label of THIS row, and 
only this row, colorised in red ?

thanks for your answer and thanks to wxpython ;)
