Row pinning

Prop enableRowPinning — engine behaviour, default false.

Guide

When to use it

Keep specific rows in view while the rest scroll — a totals row at the bottom, a highlighted record at the top.

How it works

Adds a leading pin control; pinned rows freeze to the top or bottom of the scroll area (sticky), out of the normal flow.

Gotchas

• Row virtualization yields to row pinning (pinned rows render outside the window).
• Pinning is view state — persist it with gridState if it should survive reloads.

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 },

      enableRowPinning initialState={{ rowPinning: { top: ['1'], bottom: ['5'] } }}
      styles={{ root: { maxHeight: 210 } }} pagination={false} showToolbar={false} />

Overview

Layer	enable* (engine, resolved in useBstTable)
Type	boolean
Default	false
Maps to	v9 rowPinningFeature — leading pin column; frozen top/bottom rows (sticky)
Status	✅ done
Since	v0.14.0
Settings sheet	Rows

Row pinning — freeze rows to the top/bottom of the grid via a leading pin column; pinned rows stay put across sort/filter/pagination and stick while the body scrolls. Opt-in. Default false. Maps to v9 enableRowPinning.

Enable it

<BstTableMui
  data={rows}
  columns={columns}
  enableRowPinning
/>

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

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.
