[BUG]: DetailsList does not render Dataverse Multi Select Choices

[martintoelk]

Describe the bug

As a Maker I want to add DataVerse Multiselect Choices to a DetailList Example:

The Fluent UI Details List seems to show empty columns

The new "Preview Modern Control Table Dataverse only" control is capable of rendering the Dataverse Multi Select Choices

To Reproduce Steps to reproduce the behavior:

1. Create a new Dataverse Multi Select Choices (new_multi_select_repro) in a table (new_table)
2. Create a new Custom Page
3. Add the Fluent Detailslist Control
4. Select the "new_table" in the "Record (items)" dropdown
5. Select any random view
6. ensure that the column "new_multi_select_repro" is selected in the "fields"
7. Under "Columns" add the following Power FX Code
8. Table( { ColName: "new_multi_select_repro", ColDisplayName: "Multi Select Choice Column", ColWidth: 200, ColSortable: true, ColIsBold: true, ColResizable: true } )

Expected behavior The DetailsList renders the content of the new_multi_select_repro, simliar to the "Preview Modern Control Table Dataverse only" control / Dataverse Grid

@martintoelk this is currently expected behavior as we do not support complex types in DetailsList. Workaround is to use the AddColumns() method to add the concatenated values to the Items property table passed in. You could implement this with the multiple value columns feature in DetailsList (shown as Tags) to display the values in one cell
