Table alignment

[GRGDEMA]

Probably a trivial question, but I can't set the column table alingment. I am using Jupyter/python and I have tried to write in a Jupyter cell the following code:

first cell of my Jupyter notebook

title: "Analisi andamento"
execute:
echo: false

format:
pdf:
page-layout: article
number-sections: true
toc: true
toc-title: Indice
lot: true
geometry:
- top=25mm
- bottom=20mm
- left=20mm
- heightrounded
code-fold: true
papersize: A4
fontsize: 9pt

jupyter: python3

second cell of my notebook:

#| tbl-cap: "Tabella-1"
#| tbl-colwidths: [60,40]
#| tbl-cap-location: margin
#| table-justify: right

p_oggetti=pd.pivot_table(t_grammi, index='desc_tip_gruppo', columns='ddate', values='imp_prestito', aggfunc='sum', margins = True)
p_oggetti.drop('All', axis=1, inplace=True)
p_oggetti=p_oggetti.iloc[:, [0,3,6,-1]]
pd.options.display.float_format = '{:,.0f}'.format
p_oggetti.style.set_properties(**{'text-align': 'right'})
p_oggetti

the output of the table in the Jupyter cell is correct and looks exactly like I want. When I make the quarto render the table is left aligned for all the columns.

Where is the error?

Thanks in advance, Giorgio
