Column resizing

Prop enableColumnResizing — engine behaviour, default true.

Guide

When to use it

On by default — users drag a column's border to resize it, or double-click the border to auto-fit.

How it works

Drag the header edge to set a width; double-click the resize handle to auto-size to the column's content (sampled canvas.measureText, clamped to minSize / maxSize).

Gotchas

• fitColumns suppresses the resize handles — it owns column widths while on.
• Set it false to lock widths (users can't resize).

Example source

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' },
]

export default function App() {
  return (
    <BstTableMui data={seed} columns={columns} getRowId={(r) => r.id}
      enableColumnPinning enableColumnOrdering showColumnsMenu />
  )
}

Overview

Layer	enable* (engine, resolved in useBstTable)
Type	boolean

Status	✅ done
Settings sheet	Columns

Column resizing. Maps to v9 enableColumnResizing. Default: true.

Enable it

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

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

Behavior & interactions

• Conflicts with fitColumns — manual column resizing is suppressed while fitColumns is on.
