AnnotationColumn
AnnotationColumn(
description: str = ““,
units: pint.registry.Quantity | str | None[Quantity, str, None] = None,
dtype: str =”“,
)-> None
What a set says about one of its columns.
Documenting a column never gates it: an undeclared column is carried as an extra just the same. A stated dtype is checked, so a column which says what it holds must hold it.
