DB Tree Table Header Styling

[pradiptab]

Hi

1. Is it possible to style the header of the DB Tree table bean ?
I have tried to use html, but unfortunately it only works for the area where the header text is present, not for the full header area.

2. Currently it seems like there is no way to add a onActionEvent on the table tree bean. Will it be possible to add a onAction event, and if we could get the preset dataprovider value along with the column_name on which we have clicked ?

Thanks
