The grid (core) · console.warn

column "{id}" is not movable; the move was ignored

Printed by The grid (core), prefixed [lattice], since 1.6.0.

Warnings reference › move:*

Identifier: move:*
Raised by: The grid (core)
Since: 1.6.0

What happened

The column declares layout.movable: false or layout.lockPosition, so the move - from a drag, a keyboard command or the API - was refused and the column order is unchanged.

The fix

Clear the column's movable/lockPosition layout flags if it should be movable.
