'Pretty print numpy array as table (without imports)

My question is similar to NumPy: Pretty print tabular data however, I do not wish to import any special libraries for this task.

I have a numpy array of the form:

[['Labels' '1' '5']
 ['0 O 1s    ' '0.002664922566805935' '0.11149161266806229']
 ['0 O 2s    ' '0.15992666631848482' '-0.3993420097430756']
 ['0 O 3s    ' '-0.02083386304772113' '0.19091064108525108']
 ['0 O 2px   ' '-4.787613039997692e-09' '3.3802683686891544e-09']
 ['0 O 2py   ' '0.3505418637107196' '0.61656253143151']]

However, I need to print the numbers to 5 decimal places for the core data only and not in the header. An additional problem is the table can involve any number of columns so I need a solution that can handle an unknown number of columns.

The output I am aiming for is:

Labels      1           5
0 O 1s      0.00266     0.11149
0 O 2s      0.15993    -0.39934
0 O 3s     -0.02083     0.19091
0 O 2px     0.00000     0.00000
0 O 2py     0.35054     0.61656
