The cell-editor was already complete (drafts, row-blur saves, etag
concurrency, validation). This commit adds the missing row-level ops:
- "+ Add row" appends a draft row inline; first cell focused. Row-blur
POSTs to <dir>/form.html (the existing form-create endpoint); 201
swaps the synthetic id for the server-returned URL/ETag. Empty rows
the user walks away from are silently discarded.
- Right-click a row → "Delete row" (or "Delete N rows" when a cell
range spans multiple rows). DELETE the row YAML with If-Match; 412
surfaces a conflict warning.
- Multi-row clipboard paste creates new rows for grid content that
extends past the last existing row, instead of dropping cells past
the end. Each new row saves via its own row-blur.
- Empty rows now have a 2.4em minimum height so a freshly-added row
is visible. Without the floor it collapses to cell-padding (~8px)
and looks like a divider line.
Server-side: no new endpoints. Form-create (POST <dir>/form.html →
201 + Location) and file-API DELETE carry the new client capabilities.

Bidirectional clipboard interop with Excel, Google Sheets, and any
other spreadsheet that uses RFC-4180-ish TSV on the text/plain
clipboard mime. Pasted cells write straight into the draft buffer
the same way per-key edits do; row-level save (Phase 3) picks them
up on the next row-blur with the same If-Match optimistic-
concurrency flow.
TSV parser (clipboard.js parseTSV):
- Tabs separate columns, \\n / \\r\\n separate rows.
- Quoted fields ("...") may contain tabs and newlines verbatim.
- Doubled \\"\\" inside a quoted field escapes a literal \\".
- Trailing empty row from a final \\n is dropped (Excel sends
this; matching the convention avoids a phantom blank row at
the end of every paste).
Apply-paste (clipboard.js applyPaste):
- Anchor = currently selected cell.
- 1×1 clipboard into selection → writes that one cell.
- N×M clipboard → SPILLS from the anchor down/right to
(anchor.row + N - 1, anchor.col + M - 1). Cells past the end
of either axis are silently dropped with a toast count.
- Each pasted value goes through coerceCell, which checks the
column's row-schema property type:
* number / integer → Number()
* boolean → "true"|"yes"|"1" → true; "false"|
"no"|"0"|"" → false
* everything else → raw string
Drafts hold the right JS type so the row-PUT body matches the
JSON Schema the server validates against.
Copy (clipboard.js onCopy):
- Single-cell selection: Ctrl/Cmd+C writes the cell's
effectiveCellValue (draft if dirty, else stored) as text/plain
via formatCell (RFC-4180 quoting on tab/newline/quote).
- Range copy is Phase 5 (depends on range-selection landing).
Event wiring:
- document.addEventListener('paste'/'copy') so events bubble
from any cell with focus. Phase 1's roving tabindex moves
focus around; per-cell binding would have to be re-applied
after every paint.
- onPaste bails when an editor input is mounted (the input
owns its own paste — typing into a cell editor that was just
populated with a chunk of TSV would be a footgun).
Toast for partial pastes:
When applyPaste skipped any cells, a small message in
#table-status: "Pasted N cells; M dropped (out of bounds)".
Auto-clears after 4s. Coexists with Phase 3's stale-row prompt
(toast doesn't fire if a prompt is already up; prompt outranks
toast).
Tests (6 new Phase 4 specs, total 37 in tests/tables.spec.js):
- parseTSV handles tabs, newlines, and quoted fields — covers
the parser edge cases including embedded \\n inside "..." and
doubled "" escapes.
- paste single value into selected cell — the 1×1 path; verifies
the draft buffer entry.
- paste 2×2 grid spills from anchor — the N×M spill semantic.
- paste coerces numeric/boolean values via row schema —
verifies the draft holds typeof===number for an integer column
and === true for a boolean column.
- paste out-of-bounds drops cells silently with toast — drives
via dispatched ClipboardEvent('paste') (the only way to
exercise onPaste end-to-end including the toast).
- copy single cell writes value to clipboard — synthesizes a
ClipboardEvent('copy') with a writable DataTransfer payload
and asserts the cell value lands in text/plain.
