Column Visibility Toggle in UI

[jpageacsys]

I was excited to find this library since I've been using the WinUI toolkit labs table for a while but it's a bit stale and pretty limited.
The main feature I added to that library that I don't see present here is a way for the user to toggle which columns are visible. This is helpful for my app because some users never need to know certain information in the table where others do and sometimes the table gets really large. I was able to add so I though I'd run it by everyone and see if it's something that fits the library.

Here's a screenshot of that:

It would be nice to have it in the column header flyout, but I can't think of an easy way to show columns once they are hidden unless they are in one list.

Thank you so much for your kind words about the project and for sharing your experience! I really appreciate hearing that you enjoy using it.

I think this would be a good addition to the features of the TableView and would bring a more flexible way to show/hide columns at runtime. The main thing we need to be careful about is sometimes developers want to hide certain columns for a reason, maybe for different user roles or to keep some data private. To solve this, we could add a property like CanToggleVisibility (true by default) to each column. This way, developers can make sure only safe columns appear in the toggle menu. Columns that aren’t meant to be user-toggleable wouldn’t show up in the dropdown, or if they do need to be visible, we could show them as disabled (so users can’t change them). And of course, the entire feature should be able to be turned off with a property so developers can easily make it unavailable if needed.

Thanks again for your suggestion and for your interest in improving this library!
