Keys without Enhanced Input
The Items demo driven from raw Slate key events.

What it proves
The plugin never links Enhanced Input. This is the same table with the same capabilities, bound from key events instead.
What it shares with the Items demo
Everything below the input. The same rows, the same columns, and the same event graph, built the same way in its own widget. The only difference is where the keys come from.
if ( Key == EKeys::F ) { HandleFocus(); }
else if ( Key == EKeys::R ) { HandleSort(); }
// ... one branch per key
