def set_table(self, n=100, dx=None):
        r'''Method to set an interpolation table of liquids levels versus
        volumes in the tank, for a fully defined tank. Normally run by the
        h_from_V method, this may be run prior to its use with a custom
        specification. Either the number of points on the table, or the
        vertical distance between steps may be specified.

        Parameters
        ----------
        n : float, optional
            Number of points in the interpolation table, [-]
        dx : float, optional
            Vertical distance between steps in the interpolation table, [m]
