unknown data type "{type}"; falling back to "text"

Since

1.6.0

What happened

The column declared a type that is not registered, so it is treated as text: lexical sorting, text filters, no type-driven formatting or editor. Only a type the caller actually wrote is reported - an inference that lands on text is a separate, informational line.

The fix

Use one of the built-in types, or register your own type before creating the grid.
