[O] Table sorting on two or more columns?

[James Harkins]

Is there an existing org function to sort a table based on more than one 
column? E.g., given:

| Type | Term  | Description                          |
|------+-------+--------------------------------------|
| Filt | LPF   | Butterworth lowpass filter           |
| Filt | HPF   | Butterworth highpass filter          |
| Osc  | Pulse | Band-limited pulse wave oscillator   |
| Osc  | LFSaw | Non-band-limited sawtooth oscillator |
| Osc  | Saw   | Band-limited sawtooth oscillator     |

... is there a variant of C-c ^ that will group the Types together in 
alphabetical order, and then sort each group of Terms?
