the header renderer for {kind} '{id}' threw; the stock heading is shown instead.

Raised by

The grid (rendering)

Since

1.4.0

What happened

A custom header renderer threw. The grid falls back to the stock heading for that column or group, so sorting, menus and resizing all keep working and only the custom decoration is missing.

The fix

The error is attached to the console line. A header renderer may append to the label it is given and return nothing, or return a node or a string for the grid to attach.
