[Vaadin v7] CheckBox in TreeTable header

[Thanh24 (Thanh Nguyen)]

Hello,
I need to build a TreeTable. It would be straight forward if all table column headers are Strings.
But I need a CheckBox as header of the first column. (Please take a look at the attachment image)
Could you please help me with this?
Thank you!

Hi,

you can’t place components in the header of (Tree)Table, so it won’t work quite like that. As far as I can tell, you have a couple of options:

1. create a client-side extension of TreeTable
2. use AbsoluteLayout and styles to position a CheckBox component at the wanted position
