Right click in a NumericColumn throws an error

[yves-surrel]

I simply changed the 'age' column into a NumericColumn in `traitsui/examples/demo/Standard_Editors/TableEditor_demo.py':

from traits.api import HasTraits, HasStrictTraits, Str, Int, Regex, List

from traitsui.api import (
    View,
    Group,
    Item,
    TableEditor,
    ObjectColumn,
    NumericColumn, # <---------- Change
    ExpressionColumn,
    EvalTableFilter,
)
from traitsui.table_filter import (
    EvalFilterTemplate,
    MenuFilterTemplate,
    RuleFilterTemplate,
)


# A helper class for the 'Department' class below:
class Employee(HasTraits):
    first_name = Str()
    last_name = Str()
    age = Int()
    phone = Regex(value='000-0000', regex=r'\d\d\d[-]\d\d\d\d')

    traits_view = View(
        'first_name',
        'last_name',
        'age',
        'phone',
        title='Create new employee',
        width=0.18,
        buttons=['OK', 'Cancel'],
    )


# For readability, the TableEditor of the demo is defined here, rather than in
# the View:
table_editor = TableEditor(
    columns=[
        ObjectColumn(name='first_name', width=0.20),
        ObjectColumn(name='last_name', width=0.20),
        ExpressionColumn(
            label='Full Name',
            width=0.30,
            expression="'%s %s' % (object.first_name, " "object.last_name )",
        ),
        NumericColumn(name='age', width=0.10, horizontal_alignment='center'), # <---------- Change
        ObjectColumn(name='phone', width=0.20),
    ],
    deletable=True,
    sort_model=True,
    auto_size=False,
    orientation='vertical',
    edit_view=View(
        Group('first_name', 'last_name', 'age', 'phone', show_border=True),
        resizable=True,
    ),
    filters=[EvalFilterTemplate, MenuFilterTemplate, RuleFilterTemplate],
    search=EvalTableFilter(),
    show_toolbar=True,
    row_factory=Employee,
)


# The class to be edited with the TableEditor:
class Department(HasStrictTraits):

    employees = List(Employee)

    traits_view = View(
        Group(
            Item('employees', show_label=False, editor=table_editor),
            show_border=True,
        ),
        title='Department Personnel',
        width=0.4,
        height=0.4,
        resizable=True,
        buttons=['OK'],
        kind='live',
    )


# Create some employees:
employees = [
    Employee(first_name='Jason', last_name='Smith', age=32, phone='555-1111'),
    Employee(first_name='Mike', last_name='Tollan', age=34, phone='555-2222'),
    Employee(
        first_name='Dave', last_name='Richards', age=42, phone='555-3333'
    ),
    Employee(first_name='Lyn', last_name='Spitz', age=40, phone='555-4444'),
    Employee(first_name='Greg', last_name='Andrews', age=45, phone='555-5555'),
]

# Create the demo:
demo = Department(employees=employees)

# Run the demo (if invoked from the command line):
if __name__ == '__main__':
    demo.configure_traits()

Right-clicking in an 'age' cell throws:

   1021 obj = editor.items()[row]
   1022 column = editor.columns[column]
-> 1023 menu_manager = column.get_menu(obj)
   1024 if menu_manager is None:
   1025     menu_manager = editor.factory.menu

TypeError: NumericColumn.get_menu() missing 1 required positional argument: 'row'
