Column '{colId}' names renderer '{name}', which is not registered. Register it in config.components, or use a built-in: group, checkbox, progress, link, pill, icon, skeleton.

The grid (rendering)

Since

1.0.1

What happened

The renderer name resolves neither in the grid's component registry nor among the built-ins, so no renderer is used and the cells fall back to their formatted text.

The fix

Register the component under that name, or use one of the built-ins listed in the message.

The smallest fix

createGrid(el, { components: { sparkbar: MySparkbar }, columns: [{ id: 'trend', cell: { render: 'sparkbar' } }] });
