feat(tables): column selection, keyboard shortcuts, drag reorder, and undo improvements

[waleedlatif1]

Summary

• Column selection: Click column header to select entire column, Shift+click to extend range, Ctrl+Space from any cell
• Keyboard shortcuts: Home/End, Ctrl+Home/End, PageUp/PageDown, Shift variants for extending selection, Shift+Space for full row selection, Ctrl+D fill down, Ctrl+A select all cells
• Column drag reorder: Drag via grip handle, body-level drop targets, custom drag ghost, Escape to cancel, full undo/redo
• Column header context menu: Left-click selects column, right-click opens dropdown (rename, type, sort, insert, delete)
• Delete column undo/redo: Captures column definition, cell data, order, and width for full restoration
• Auto-resize on double-click: Double-click column border to fit content, padding matches Google Sheets
• Right-click preserves selection: Right-clicking within an existing selection keeps it intact
• Error feedback: Column type change incompatibility now shows toast notification instead of failing silently
• Partial update fix: updateRow now merges partial updates to prevent column data loss from Mothership calls
• Scroll-into-view: Selection focus (not just anchor) is scrolled into view during Shift-extend operations
• Accessibility: Proper aria-hidden values and aria-label on column header controls

Test plan

• Click column header to select full column, Shift+click another header to extend
• Right-click column header opens context menu (rename, change type, sort, insert, delete)
• Drag column via grip handle to reorder, press Escape mid-drag to cancel
• Ctrl+Z/Y undoes/redoes column reorder, column delete, and type changes
• Delete column, then Ctrl+Z restores column with all data, order, and width
• Change column type to incompatible type (e.g. text with letters to number) shows toast error
• Home/End/PageUp/PageDown navigate correctly, Shift variants extend selection
• Ctrl+D copies top cell value down through multi-row selection
• Shift+Space selects entire row
• Double-click column border auto-resizes to fit content
• Right-click within existing selection preserves it
• Shift+Arrow scrolls viewport to keep focus cell visible

PR Summary

Medium Risk
Moderate risk due to substantial changes to table editing interactions (selection/shortcuts/drag-drop) and undo/redo semantics, plus row-update behavior changes that affect data persistence and validation paths.

Overview
Tables UI now supports spreadsheet-style selection and navigation. Column headers can be clicked/shift-clicked (and Ctrl+Space) to select full columns, Shift+Space selects full rows, and new keyboard handling adds Home/End, PageUp/PageDown, and Ctrl+D fill-down; right-clicking inside an existing selection no longer resets it.

Column operations are expanded and integrated with undo/redo. Column drag-reorder is improved (body-level drop targeting, clearer indicators, Escape-to-cancel) and now records a reorder-columns undo action; column delete supports multi-column deletion and records a delete-column undo snapshot (schema attrs, cell data, widths/order) to restore on undo.

Data/UX correctness fixes. updateRow now merges partial updates server-side (API routes stop pre-merging), preventing unintended column wipes; bulk clear/cut operations batch row updates; column type-change failures now toast on error; file uploads run in parallel and message submit is blocked while attachments are still uploading.

Greptile Summary

This PR adds column selection (click/Shift+click header, Ctrl+Space), column drag reorder with undo/redo, a full suite of keyboard shortcuts (Home/End/PageUp/PageDown/Ctrl+D fill-down/Shift+Space row-select), auto-resize on double-click, and fixes updateRow to merge partial updates instead of replacing the entire row. All P0/P1 issues from the prior review round (column-width wipe on delete undo, DOM span leak in auto-resize, missing columnRequired on delete undo, stale schema position for multi-column delete, silent cell-data restoration failure) have been resolved in follow-up commits.

Confidence Score: 5/5

Safe to merge; all prior P0/P1 findings are resolved and no new blocking issues were found.

All six issues flagged in the previous review round have been addressed in follow-up commits (column-width wipe, DOM span leak, columnRequired capture, stale position on multi-delete, cell-data restoration error handling, duplicate undo on drag). The remaining findings are P2: a stale closure in a cleanup effect, a cosmetic drag-ghost edge case, and a harmless redundant state reset on the Escape-cancel path. None affect correctness of the primary table operations.

apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/copilot/components/user-input/hooks/use-file-attachments.ts — cleanup effect stale closure.

Important Files Changed

Filename	Overview
apps/sim/app/workspace/[workspaceId]/tables/[tableId]/components/table/table.tsx	Core table component; adds column selection, drag reorder, keyboard shortcuts, auto-resize, and related undo capture. Logic is carefully ref-gated; all state inside the empty-dep keydown effect is accessed via refs.
apps/sim/hooks/use-table-undo.ts	Adds reorder-columns case, getColumnWidths callback, onError for cell-data restore, and columnRequired to delete-column undo. All prior audit findings addressed.
apps/sim/lib/table/service.ts	updateRow now merges partial updates before validation and write; unique-constraint check continues to exclude the current row.
apps/sim/lib/table/tests/update-row.test.ts	New test file covering partial merge, single-column update, explicit null, full update, and missing-row cases.
apps/sim/stores/table/types.ts	delete-column action now includes columnRequired; reorder-columns action added; types match all capture and restore sites.
apps/sim/stores/table/store.ts	patchRowIdInEntry now handles delete-column cellData rows; store logic is correct and idiomatic Zustand with devtools.
apps/sim/app/api/table/[tableId]/rows/[rowId]/route.ts	PATCH route delegates partial-merge logic to service.ts; error classification unchanged.
apps/sim/app/api/v1/tables/[tableId]/rows/[rowId]/route.ts	v1 PATCH inherits partial-merge via shared service.ts; rate-limiting and workspace-scope checks are in place.
apps/sim/hooks/queries/tables.ts	Query hooks unchanged in functionality; optimistic updates use onSettled correctly.
apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/copilot/components/user-input/hooks/use-file-attachments.ts	Adds restoreAttachedFiles; the existing cleanup useEffect has an empty dep array so preview URLs won't be revoked if the component unmounts while files are still attached.
apps/sim/app/workspace/[workspaceId]/home/components/user-input/user-input.tsx	Minor import additions; no functional concerns.
