I want to hide headers in the details header pane that have null values in the details pane.

in the visible expression I tried

=IF(ISBLANK([10]);"False"; "True")
but this only checks the first value of the value set.
oct | null | dec
1 | null | 1
1 | 1 | 1
i also tried
=IF(ISEMPTYDATA([10]);"False"; "True")

but displays the header when there is no data for example
[i dont want oct displayed if null] http://i.stack.imgur.com/p8gQA.png
