Support for 'veryHidden' sheets not supported

[srefsum]

Excel supports two modes of hidden sheets:

• hidden
• veryHidden

veryhidden is only available from the vba editor.

It can be implemented this way:

I failed to implement a test case that actually works; but for my installation of office the mentioned code gives the required result.

Seems like a reasonable suggestion. I'll look into it.

I've added a fix for this to main via the $worksheet->very_hidden() method.
