Per-column edit lock

Prop showColumnEditToggle — adapter chrome, default false.

Guide

When to use it

Let an end-user make an editable column read-only at runtime — no code change, no redeploy.

How it works

Adds a per-column lock / unlock (✏️) control to the columns menu that overrides the column's meta.editable at runtime via runtime.setColumnEditable.

Gotchas

• Requires enableEditing — there's nothing to lock without an edit session.
• It's an adapter control, not a settings-sheet toggle.

import React from 'react'
import { BstTableMui } from '@bloomskill/table-mui'
import type { BstTableColumn } from '@bloomskill/table-engine'
import '@bloomskill/table-engine/styles.css'
type Row = { id: string; name: string; team: string; role: string; score: number }
const seed: Row[] = [
  { id: '1', name: 'Ada Lovelace',    team: 'Platform', role: 'Engineer',  score: 92 },
  { id: '2', name: 'Alan Turing',     team: 'Research', role: 'Scientist', score: 88 },
  { id: '3', name: 'Grace Hopper',    team: 'Platform', role: 'Engineer',  score: 95 },
  { id: '4', name: 'Katherine J.',    team: 'Research', role: 'Analyst',   score: 90 },
  { id: '5', name: 'Edsger Dijkstra', team: 'Platform', role: 'Architect', score: 84 },
]
const columns: BstTableColumn<Row>[] = [
  { id: 'name', accessorKey: 'name', header: 'Name' },
  { id: 'team', accessorKey: 'team', header: 'Team' },
  { id: 'role', accessorKey: 'role', header: 'Role' },
  { id: 'score', accessorKey: 'score', header: 'Score', sortFn: 'basic' },
]
const editable: BstTableColumn<Row>[] = columns.map((c) =>
  c.id === 'name' || c.id === 'score'
    ? { ...c, meta: { type: c.id === 'score' ? 'number' : 'text', editable: true } }
    : c,
)
export default function App() {
  const [rows, setRows] = React.useState(seed)
  // Open the Columns menu → lock / unlock a column's editability at runtime.
  return (
    <BstTableMui data={rows} columns={editable} getRowId={(r) => r.id}
      enableEditing showColumnEditToggle showColumnsMenu onDataChange={setRows} />
  )
}

Overview

Layer	show* (chrome, resolved in the adapter)
Type	boolean
Default	false
Maps to	adapter Columns-menu lock/unlock (✏️) per editable column → engine runtime.setColumnEditable overrides meta.editable at runtime (store columnEdit). Requires enableEditing. Not a BstTableEngineToggles flag (no settings-sheet entry)
Status	✅ done
Since	v0.27.0

Enable it

<BstTableMui
  data={rows}
  columns={columns}
  enableEditing          // chrome is a no-op without its behaviour flag
  showColumnEditToggle
/>

Swap BstTableMui for BstTableShadcn (and the CSS import) for the shadcn skin — same props.

Behavior & interactions

• Requires enableEditing to be on — this flag is a no-op otherwise.

Spec coverage

Spec codes (A1, C2, X8, …) are Bst-Table's internal requirement IDs from the capability matrix; P0–P2 mark the delivery phase. They are traceability tags, not part of the public API.

• F3 · Disable column — ✅ built. P3 — meta.disabled
