Description
Hi,
First, thank you again for the ability to translate the calendar's buttons! I am still working on my big form for work and something else has arised.
We have decided to use nested headers to group columns together, because of a common characteristic or because they're repeatable. We currently have between ~60 to ~130 columns, we implemented a way to hide not needed ones but nested headers aren't recomputed, thus causing some confusion.
Before hiding,

After hiding "P** - 3 > Mesure P", "Smin - 1 > Mesure (E(MPa))" and "Smin - 1 > Mesure V%",

Is there a way to refresh nested while using hidden columns?
Thanks.
