I'll create a drag and drop table with mapping functionality where you can drag items from an external source into table cells for field mapping.

I've created a comprehensive drag and drop field mapping interface with the following features:

Key Features:

1. Source Fields Panel: Draggable fields with type indicators
2. Target Table: Droppable cells for mapping fields

3. Visual Feedback:

   • Drag states with opacity changes
   • Drop zones with border highlights
   • Used field indicators

4. Mapping Management:

   • Remove individual mappings
   • Clear all mappings
   • Required field validation

5. Status Tracking:

   • Progress indicators
   • Required vs optional field status
   • Mapping completion summary

How to Use:

1. Drag: Click and drag any field from the left panel
2. Drop: Drop it into any "Drop field here" area in the table
3. Remove: Use the trash icon to remove mappings
4. Validate: Required fields are highlighted and tracked

The interface prevents duplicate mappings by showing already-used fields as disabled and provides clear visual feedback throughout the drag and drop process.
