                 df = pd.read_csv('wyjebany.csv')

                 df = df[~df.HOME.str.contains('Beach|Futsal')]
                 df = df[~df.COUNTRY.str.contains('Germany Oberliga NOFV|France  Youth U19 
                           League|Portugal Champions NACIONAL Juniores A 1|Spanish Bizkaia-Tercera')]
                df = df.replace(to_replace='Division|League|Liga|Footbal|Primavera', value='', 
                           regex=True)
                           # df = df.replace(to_replace='.', value='', regex=True)
                print(df)
                print(df.columns)

               app.layout = dash_table.DataTable(

                                columns=[{"name": i, "id": i} for i in df.columns],
                               row_selectable='multi',
                               sort_action='native',
                              # editable=True,
                              row_deletable=True,
                             # rows=[{}],
                             selected_rows=[],

                           css=[{'selector': 'tr:hover',
                           'rule': 'background-color:  #80FF80',
                                # 'font-family': 'Times New Roman',

                                       }],
                         html.Div(id='hidden-div', style={'display': 'none'},
                 ),

here is my callback function

            @app.callback(
    dash.dependencies.Output('hidden-div', 'style'),
    [dash.dependencies.Input('table', 'columns'),
    dash.dependencies.Input('table', 'selected_rows')])
def print_value(columns,selected_rows):
    print("Hi i am triggered")
    # for i in selected_rows:
    #     print(i)
    selected_rows = [columns[i] for i in selected_rows]
    # selected_rows = pd.DataFrame(rows).iloc[i]
    print(selected_rows)
    style = {'display': 'none'}
    return style

your dash table is missing id, and also give html.div outside the table.
dash_table.DataTable(id='table,
…
),
html.Div(id=‘hidden-div’, style={‘display’: ‘none’})

the second input should get “chosen_rows” parameter instead of “selected_rows”
