Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR improves table drag feedback by adding source highlighting and a native drag preview, but multi-editor pages may lose an active preview when another editor is destroyed, and concurrent table edits may still cause drag decorations to fail; a small stylesheet compatibility cleanup is also needed.

@mustafa-yilmaz the screen recording looks great. With the way that you implemented it, it only is changed in the one example, whereas I think that it would be great to have both the drag preview & drop zone styling by default in the blocknote table implementation. Would you mind porting that over so that it can be part of the project as a whole? I'm not sure that we want to go for the table CSS changes at this time, we can leave that in your example if people ever want to port that into their application. The thing that interests me more for the project is to move over the drag preview & drop zone parts. Thanks for contributing to the project! |

…state Addresses review on TypeCellOS#2920 (r3798069357): the try/catch only covered `state.doc.resolve(tablePos + 1)`, so everything after it was still unprotected. `posAtIndex` calls `node.child()` internally and throws a RangeError when the index is out of range, which is reachable two ways - `tablePos` still resolving but no longer pointing at the table, and the row/column counts coming from `state.block`, a snapshot taken on hover that can exceed what's in the document by the time it's used. The decoration build moves into `getTableDragDecorations`, which the plugin prop calls inside a single try/catch, so a stale position or index anywhere in it - including the drop-cursor branches, which were never covered - skips the decorations instead of throwing out of the plugin. It also checks the resolved node really is a table before indexing into it. This still isn't a fix for the underlying staleness (TypeCellOS#2921), which needs `tablePos` remapped through `tr.mapping`; it keeps the editor alive until then. Also clears the drag image in `TableHandlesView.destroy()`. Cleanup otherwise only runs from `dragEnd`, which never arrives if the editor is torn down mid-drag, leaving the copy in the DOM and the module-scope reference set.

On the two nitpicks from the last review:
That declaration is pre-existing; this PR only changed the selector in front of it, from The two properties aren't interchangeable here. Happy to do it as a separate change if maintainers want the deprecation cleaned up — it deserves its own before/after check on narrow columns with long unbroken words. |
|
On the 🟡 Moderate merge-risk flag ("a concurrent document edit during dragging can still trigger an out-of-range position error… A targeted fix or explicit owner acceptance is needed before merge") — deferring, with maintainer agreement. Detail below so the call is on the record rather than implied. What is guarded as of 225c1cc The whole decoration build now runs inside a single What is not fixed The underlying staleness. Why it is deferred rather than fixed here Remapping Net effect for this PR: it makes the reported crash path survivable and does not extend the underlying issue. |
|
Correcting my comment above about the merge-risk flag: the reasoning in it is out of date, and one commit here needs revisiting on rebase. I said the stale- That has a direct consequence for I would rather fix that than leave a misleading justification in the history, so on rebase onto current Nothing about the actual feature in this PR changes: the drag preview and the drag-source highlight are unaffected, and the merge-risk flag itself should now be moot, since the failure it points at is fixed upstream. |
Dragging a table row or column gave almost no feedback: a drop cursor at the target position, and a deliberately hidden 1x1 native drag image, so nothing followed the cursor and nothing marked what was being moved. Both are now part of the TableHandles extension, hanging off the drag state it already keeps: - The cells of the row/column being dragged get a `bn-table-drag-source` class, via node decorations added alongside the existing drop-cursor widgets. Both are resolved with getCellsAtRowHandle / getCellsAtColumnHandle, so merged cells are handled the same way the drop cursor already handles them. The highlight is shown for the whole drag, including while the cursor is outside the table or over a position that can't be dropped into - only the drop cursor is conditional on that. - The hidden drag image is replaced by a copy of the cells being dragged, so the content visibly follows the cursor. Cells are copied at their measured on-screen size, which reproduces the widths the <colgroup> supplied and flattens merged cells. The copy is appended next to the editor and inherits the editor's classes, minus the ones identifying it *as* the editor (SideMenuView measures every .bn-editor in the document, and this isn't one) - the same filtering the side menu's own drag preview does. Table styles are matched against `:is(.bn-editor, .bn-table-drag-preview)` so they reach the copy; :is() takes its most specific argument, so the selectors stay exactly as specific as they were and existing overrides are unaffected. Layout properties set on `.ProseMirror table`, which the copy is outside of, are carried over explicitly, as are the width and minimum width the table is given inline - the latter covers every column, so a copy holding one column would otherwise be stretched to the width of the whole table. Also guards the decorations against a stale `tablePos`: it's captured on hover and isn't remapped, so a concurrent edit elsewhere in the document mid-drag could make it resolve out of range and throw out of the plugin (TypeCellOS#2921). Skipping the decorations is enough to keep the editor alive. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`unsetTableDragImage()` only ran from `setTableDragImage` and `dragEnd()`, and `dragEnd()` throws before reaching it when `view.state` is undefined. If the editor is torn down mid-drag the copy is left in the DOM with the module-scope reference still set. Raised in review on TypeCellOS#2920 (r3798069357). The stale-position guard from the same review is not carried over: TypeCellOS#2972 fixed the underlying issue (TypeCellOS#2921) by resolving the table position against the document being rendered, so `decorations` can no longer be handed a stale one.

Addresses review on TypeCellOS#2920 (r-4981596549). `dragImageElement` was module state, so the `destroy()` cleanup added in the previous commit removed the drag image for *any* editor rather than the one being destroyed. With more than one editor on a page - or a nested editor inside a custom block - unmounting one would have cleared a preview that another editor was still dragging. The cleanup introduced that; the module scope predates it. The element is now a private field on `TableHandlesView`, with `setDragImage` and `unsetDragImage` methods owning its lifecycle, and `buildTableDragImage` left as a pure builder. Also replaces the deprecated `word-break: break-word` on the table rule. The earlier suggestion of `overflow-wrap: break-word` was declined because it changes the min-content contribution that table column sizing depends on; `word-break: normal` + `overflow-wrap: anywhere` is what the deprecated value is defined to mean, so it carries that effect and is an exact swap. The drag-image width test covers the column sizing either way. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Summary
Dragging a table row or column gives almost no feedback today: a drop cursor at the target position, and a deliberately hidden 1x1 native drag image, so nothing follows the cursor and nothing marks what is being moved.
This adds both to
TableHandlesExtensionitself, so they are the default rather than something each app has to rebuild:bn-table-drag-sourceclass, so it stays clear what is moving.How it works
Both hang off the drag state the extension already keeps, and cells are resolved with the same
getCellsAtRowHandle/getCellsAtColumnHandlehelpers the drop cursor already uses, so merged cells are handled consistently.The highlight is added as node decorations alongside the existing drop-cursor widgets. It stays for the whole drag, including while the cursor is outside the table or over a position that can't be dropped into — only the drop cursor remains conditional on that.
The drag image is a copy of the dragged cells, appended next to the editor. A few details worth calling out for review:
bn-editor,bn-root,ProseMirror).SideMenuViewmeasures every.bn-editorin the document, and this isn't one — this is the same filtering the side menu's own drag preview already does.:is(.bn-editor, .bn-table-drag-preview)so they reach the copy.:is()takes the specificity of its most specific argument, so those selectors stay exactly as specific as they were and existing app-level overrides are unaffected.width/min-width/max-widththe real table carries inline are dropped. Thatmin-widthcovers every column, so a copy holding a single column would otherwise be stretched to the width of the whole table.table-layout,border-collapseandborder-spacingare carried over from the real table. They're set on.ProseMirror tableand the copy sits outside it, so without this the browser defaults apply and every border between the copied cells is drawn twice.Rebased onto current
main. An earlier revision of this PR also added atry/catcharound the decoration build, as a backstop for a staletablePos(#2921). #2972 has since fixed that properly —getTablePosnow resolves the position against the document being rendered — so the guard has no cause left to defend against and has been dropped rather than carried over with a justification that no longer holds. The second commit here keeps the one piece of it that was always independent: clearing the drag image when the view is destroyed, sincedragEndnever arrives if the editor is torn down mid-drag.Test plan
