ig.excel.HiddenColumnCollection

A collection of hidden WorksheetColumn instances.

Remarks

The columns in this collection do not necessarily have their RowColumnBase.hidden property set to True. This collection applies to a HiddenColumnCollection.worksheet, but belongs to a CustomView. When the CustomView which owns this collection is applied, the columns in this collection will have their RowColumnBase.hidden property set to True. All other columns in the associated worksheet will be made visible.
