RowList

Represents rows of the [DataFrame].

Refrain from accessing data via [RowList] and [Row] in performance-critical scenarios. To maximize performance, get values via [DataFrame.columns], instead.

Constructors

new RowList(table, dart): RowList

Parameters

Parameter	Type
table	DataFrame
dart	any

Returns

RowList
