What happened

The decoration's type is not one the renderer implements, so the decoration is dropped entirely and the cells render plain. No guess is made at what was meant.

The fix

Use one of the decoration names listed in the message.

The smallest fix

columns: [{ id: 'state', cell: { decoration: { type: 'pill' } } }]
