    I am building a FLET app, but sometimes I have a datatable which is too large for the frame it is in. For the row I have a scrollbar appearing, but for the column I just don't seem to get it working.

    In this code a scrollbar simply does not appear.

    import pandas as pd
    pd.options.display.max_columns = 100
    from services.bag import PCHN
    from utils.convertors import dataframe_to_datatable
    import flet as ft

    def main(page: ft.page):
    def bag_service(e):
    pc = '9351BP' if postal_code_field.value == '' else postal_code_field.value
    hn = '1' if house_number_field.value == '' else house_number_field.value
    address = PCHN(pc,
    hn).result
    bag_container[0] = dataframe_to_datatable(address)
    page.update() # This is not updating my bag_table in place though. It stays static as it is.

    # define form fields
    postal_code_field = ft.TextField(label='Postal code')
    house_number_field = ft.TextField(label='House number')
    submit_button = ft.ElevatedButton(text='Submit', on_click=bag_service)

    # fields for the right column
    address = PCHN('9351BP', '1').result
    bag_table = dataframe_to_datatable(address)
    bag_container = [bag_table]

    # design layout
    # 1 column to the left as a frame and one to the right with two rows
    horizontal_divider = ft.Row
    left_column = ft.Column
    right_column = ft.Column

    # fill the design
    page.add(
    horizontal_divider(
    [left_column(
    [postal_code_field,
    house_number_field,
    submit_button
    ]
    ),
    right_column(
    [
    ft.Container(
    ft.Row(
    bag_container,
    scroll='always'
    ),
    bgcolor=ft.colors.BLACK,
    width=800,)
    ],scroll='always'
    )
    ]
    )
    )

    if __name__ == '__main__':
    ft.app(target=main,
    view=ft.WEB_BROWSER,
    port=666
    )


    I am lost as to what could be the case here. Any help would be much appreciated.
