I apologize if I am making a silly mistake, but I am unable to get the NIST data table when using multiple element names while using astroquery.nist.

Using

```auto
from astroquery.nist import Nist
Nist.query((np.around(6500,2)-0.1)*u.AA, (np.around(6550,2)+0.1)*u.AA, linename='Al',wavelength_type='vac+air')

```

gives me a table, but using

```auto
from astroquery.nist import Nist
Nist.query((np.around(6500,2)-0.1)*u.AA, (np.around(6550,2)+0.1)*u.AA, linename='Al;Ba',wavelength_type='vac+air')

```

does not.

Any help will be greatly appreciated!
