Changes

1. Custom CollectionView Implementation

   • Replaced CommunityToolkit.WinUI.Collections/AdvancedCollectionView with an internal CollectionView type to avoid conflicts with external dependencies. #52
   • The TableView.CollectionView property has been removed.
   • Introduced two new properties to manage custom sorting and filtering:
     • SortDescriptions: A collection of sort descriptions applied to the items.
     • FilterDescriptions: A collection of filter descriptions applied to the items.

2. Auto Generate Columns for Primitive types

   • There will be a single column with empty Binding and Headerif theItemsSourceis a collection ofPrimitive` types.

3. Enhanced Property Access for Operations

   • Added a new virtual method in TableViewColumn to retrieves cell content for sorting, filtering, copying, and exporting operations:

     public virtual object? GetCellContent(object? dataItem)

4. Improved Value Handling

   • Sort, filter, copy, and export operations now leverage converters defined in the column's Binding to obtain the final value.#26
