class Table(object):
    """
    A display widget for a table of values, based on a ``MultiListbox``
    widget.  For many purposes, ``Table`` can be treated as a
    list-of-lists.  E.g., table[i] is a list of the values for row i;
    and table.append(row) adds a new row with the given lits of
    values.  Individual cells can be accessed using table[i,j], which
    refers to the j-th column of the i-th row.  This can be used to
    both read and write values from the table.  E.g.:

        >>> table[i,j] = 'hello'

    The column (j) can be given either as an index number, or as a
    column name.  E.g., the following prints the value in the 3rd row
    for the 'First Name' column:

        >>> print(table[3, 'First Name'])
        John

    You can configure the colors for individual rows, columns, or
    cells using ``rowconfig()``, ``columnconfig()``, and ``itemconfig()``.
    The color configuration for each row will be preserved if the
    table is modified; however, when new rows are added, any color
    configurations that have been made for *columns* will not be
    applied to the new row.

    Note: Although ``Table`` acts like a widget in some ways (e.g., it
    defines ``grid()``, ``pack()``, and ``bind()``), it is not itself a
    widget; it just contains one.  This is because widgets need to
    define ``__getitem__()``, ``__setitem__()``, and ``__nonzero__()`` in
    a way that's incompatible with the fact that ``Table`` behaves as a
    list-of-lists.

    :ivar _mlb: The multi-column listbox used to display this table's data.
    :ivar _rows: A list-of-lists used to hold the cell values of this
        table.  Each element of _rows is a row value, i.e., a list of
        cell values, one for each column in the row.
