dfBindings()
dfBindings(
df,scope):BindSource
Defined in: js-api/src/u2core/df-bindings.ts:71
The BindSource over a DataFrame signal. Subscriptions and signals live on scope.
Lazy: a currentRow.<col> signal is created on first bindStep and cached; a repoint (the
frame signal changing identity) resubscribes events and refreshes every cached signal.
A column step always answers a signal — an absent frame or column reads undefined and
refuses writes, so bound inputs show empty instead of breaking (the containment posture).
