Hi,

Regarding your questions:

1. JSX cannot be used as column template. The column template expects HTML String to be set to formatObject’s template property.
2. The column’s template property is indeed ‘any’ by design, because it could be multiple different things like ‘string’, ‘id’, ‘HTMLTemplateElement’ or function.
3. This is a missing functionality. We will create a work item for implementing it.

Best regards,
