  they have equal heights.

docstr: Create an axes locator callable for the specified cell.
  
  Parameters
  ----------
  nx, nx1 : int
      Integers specifying the column-position of the
      cell. When *nx1* is None, a single *nx*-th column is
      specified. Otherwise, location of columns spanning between *nx*
      to *nx1* (but excluding *nx1*-th column) is specified.
