class_docstr: Extends QTableWidget with some useful functions for automatic data handling
  and copy / export context menu. Can automatically format and display a variety
  of data types (see :func:`setData() <pyqtgraph.TableWidget.setData>` for more
  information.
code: def iterate(self, data):
      # for numpy.void, which can be iterated but mysteriously
      # has no __iter__ (??)
      for x in data:
          yield x
  
imports: import numpy
  from ..Qt import QtCore, QtGui, QtWidgets
label_desc: Use image node_id 9 for calling the TableWidget obj's underlying member method code with example usage: obj.iterate(data) without return types
