convert MATLAB table column from array of doubles to string

Question

I'm having trouble converting a column in my MATLAB table. Each row of this column contains a 802x1 double. For each row in this column, I'd like to merge all of the numbers into one large string (basically so I can have a flat table instead of a nested table). I'm able to do it for one row at a time using: >> num2str(reshape(data.Wavelength{1}',1,{})) but is there a way to do them all in a cell function? How do I go about this when the data is already in a table format?
