Column pinning

Prop enableColumnPinning — engine behaviour, default false.

Guide

When to use it

Keep key columns — an id, a name, an action column — visible while the rest scroll horizontally.

How it works

Adds pin-left / pin-right controls to the columns menu; pinned columns become sticky at the edges of the scroll area. State is { start, end } column-id lists.

Gotchas

• Surface the control with showColumnsMenu.
• Column virtualization falls back to rendering all columns while pinning is active (the two don't stack).
• The row-number column (enableRowNumbers) pins to the start ahead of user pins.

Overview

Layer	enable* (engine, resolved in useBstTable)
Type	boolean
Default	false
Maps to	v9 enableColumnPinning (state {start,end})
Status	✅ done (Phase 3)
Since	v0.7.0
Settings sheet	Columns

Column pinning (sticky left/right). Maps to v9 enableColumnPinning. Default: false.

Enable it

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

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