    These functions are not meant to be used directly.  Instead, they will be
    automatically called when their names are used as values for the `formatter`
    property in a columnd definition.
    They will be called just once per rendering cycle and will receive
    the column configuration.  They are expected to return a function that will
    then be called once per row and will do the actual formatting.
    They are expected to do all the preparatory once-per-render work
    so that the actual formatting function doesn't need to repeat it.
