[Enhancement Contribution Request] Enriched Reordering Visualisation for Tables

[mustafa-yilmaz]

My sincere greetings to the maintainers and community behind this useful initiative.

Would it be possible for me to contribute the enhancement displayed in the video below, which I developed with the assistance of Claude Sonnet 5.0?

Since the output was generated with the help of an AI tool, I thought it would be better to ask first in case any additional review steps, checks, or requirements should be completed before I open a pull request.

The enhancement itself is available here.

AI assistance is not a problem by itself; what matters is that the contributor can explain the design, the code has the project's license, and the change passes the normal review and test requirements.

For this enhancement, I would suggest opening a focused PR against BlockNote rather than asking maintainers to review the comparison in another repository. The PR should include:

• a short explanation of the interaction model;
• a minimal reproduction or demo for table row reordering;
• tests for keyboard, pointer, touch, and cancelled drags;
• behavior when rows contain nested blocks, images, or merged cells;
• accessibility behavior and focus restoration after a reorder;
• performance behavior for a large table.

The visual effect is only one part of the feature. The important contract is that the document order, selection, undo/redo history, and collaboration updates all remain correct when a drag is interrupted or two users edit the table at the same time.

I would also rebase the implementation onto BlockNote's current table abstractions instead of copying framework-specific code from the external comparison. A small PR with the demo and tests first will give maintainers a much easier way to decide whether the interaction belongs in core or in an extension.

@farfromexact,

Thanks so much for the detailed guidance.

Watching an exchange between two AIs in PR #2920 became a really surprising experience for me.
