Moves table drag source highlighting, drop cursor decorations, and a floating drag preview into TableHandlesExtension so they work out of the box — no extensions or hooks needed.
Adds an example (21-table-reordering-visualization) that reskins the built-in drag affordances via CSS custom properties (with dark-mode support) for a Microsoft Loop-style look.
Adds unit tests for the new dragDecorations and dragPreview modules, plus e2e screenshot tests for the drag-in-progress state.
Test plan
Unit tests pass (vp run test)
E2e tests pass (vp run e2e)
Open the table reordering example in the playground and verify:
Dragging a row/column shows a tinted highlight on the source
A floating snapshot follows the cursor
A drop indicator marks the target position
Reorder completes correctly on drop
Verify dark mode styling works in the example
Summary by CodeRabbit
New Features
Added clearer visual feedback when dragging table rows and columns, including source highlights, drop indicators, and previews that retain the editor’s styling.
Added a table-reordering example with customizable styling and header rows for newly inserted tables.
Documented table-drag styling options and CSS selectors.
Bug Fixes
Improved drag-preview cleanup when a drag ends or its table is removed or replaced.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Table row and column dragging now uses dedicated source and drop-cursor decorations and rendered drag previews. The change adds preview cleanup, automated coverage, and a styled example with documentation. PDF exporter tests also provide a file URL resolver.
A new helper creates source-cell decorations and validates drop-cursor targets. The table handles extension delegates decoration generation to the helper. Editor CSS styles dragged rows and columns. Tests cover target validation, merged cells, stale positions, and large tables.
Table drag images use cloned row or column snapshots attached to an editor-specific container. The extension removes previews on drag completion and teardown. Tests cover preview contents, styling, attachment, and cleanup.
Visualization example and documentation examples/03-ui-components/21-table-reordering-visualization/*, docs/content/docs/react/styling-theming/overriding-css.mdx, playground/src/examples.gen.tsx
The example adds table styling, initial table content, and a custom /table menu item that inserts a header row. Its README and CSS reference describe drag styling and preview behavior.

Selected table-cell colors can disappear in headers and on hover in the example. This is a bounded visual issue; the preview attachment assertion can also be tightened.

dragOverHandler dispatches a dummy transaction on every index change. Without a key, ProseMirror cannot compare widget decorations and rebuilds the DOM for each cursor on each redraw. A key derived from the orientation and target index lets ProseMirror reuse the widget when nothing changed.

Scope the preview to the editor view instead of a module singleton.
dragImageElement is module state shared by every editor on the page. TableHandlesView.destroy calls unsetTableDragImage() unconditionally, and dragEnd does the same. If a page mounts two editors and one unmounts or ends a drag, it clears the preview owned by the other editor. Keying the preview by view removes the cross-editor coupling.

-let dragImageElement: HTMLElement | undefined;+const dragImageElements = new WeakMap<EditorView, HTMLElement>();

Expose the drag accent colour as a custom property.
The accent #adf is hard-coded in three rules: the drop cursor background, the source outline, and the preview cell border. Lines 89-90 already use var(--bn-colors-..., fallback). The PR describes an example that customizes these affordances with CSS custom properties. A single token keeps the three rules in sync and gives consumers one override point.

getTableDragDecorations inserts the cursor inside each target td/th, but those cells are not positioned. The nearest positioned ancestor is .tableWrapper, so the cursor can span the full table instead of the target cell. Add position: relative to the table cell rule.

CSS Text specification word-break break-word deprecated equivalent overflow-wrap anywhere word-break normal
💡 Result:
The CSS keyword value word-break: break-word is officially deprecated [1][2]. It is maintained in specifications primarily for backward compatibility with legacy content [1]. When you specify word-break: break-word, the browser interprets it as having the same effect as the combination of word-break: normal and overflow-wrap: anywhere [3][1][4]. To achieve this same behavior using modern, standard-compliant CSS, you should use the following declaration [5][6]: overflow-wrap: anywhere; While overflow-wrap: break-word is another common option, overflow-wrap: anywhere is generally preferred because it also considers the soft wrap opportunities introduced by the break when calculating min-content intrinsic sizes [1][7][8]. This often prevents issues where containers might otherwise expand unexpectedly [6][8]. If you need to ensure standard text-breaking behavior alongside this, you may explicitly set word-break: normal, though it is the default value for most elements [3][1].

Tighten the container assertion. It cannot detect a fallback to document.body.
The test claims the snapshot must sit inside the editor's container and not in document.body. The assertion checks mountPoint.parentElement!.contains(preview). That parent is usually document.body, so the assertion also passes when attachDragPreview falls back to root.body. A regression to the fallback would not fail this test.

Preserve user-selected cell colors.
These selectors override BlockNote’s color attributes. Header cells ignore selected text and background colors, and body cells lose their background color on hover. The example enables both color controls in App.tsx. (raw.githubusercontent.com)
Apply header defaults only when the corresponding color attribute is absent. Preserve colored backgrounds during hover.

Update the table header and body-cell rules in tableStyles.css so default header
text and background colors apply only when the corresponding BlockNote color
attribute is absent; ensure hover styles do not override user-selected cell
background colors.
