How to concatenate elements of different type in a table cell?

[Larz60+]

You should be able to convert the numpy array to a list like:

import numpy as np

your_nump_array = [] # replace with your data
plist = np.array(your_nump_array).tolist()
print(plist)

I'm not a big user of numpy, so you may have to play with this a bit.
