How to select only one row in DataTable (at the same time) ?

[nastiliano]

Hello everyone.

I can't find how to select only one row and no other.

I want to select only one row at a time and, then, when I select another, deselect the selected one and select the new one (automatically)

Somebody could help me?

Thanks and best regards!!

My unorthodox own solution:

import flet as ft

def main(page: ft.Page):

    def clear_chk(e):
        for i in range(len(table.rows)):
            table.rows[i].__setattr__("selected" , False)
        page.update()

    table = ft.DataTable(columns = [ft.DataColumn(ft.Text("Column 1") ,
                                                 ) ,
                                    ft.DataColumn(ft.Text("Column 2") ,
                                                  numeric = True
                                                  )
                                   ] ,
                        rows = [ft.DataRow([ft.DataCell(ft.Text("A")) , ft.DataCell(ft.Text("1"))] ,
                                           on_select_changed = lambda e: [clear_chk(e) , e.control.__setattr__("selected" , True) if e.control.selected 
== False else e.control.__setattr__("selected" , False) , page.update()]
                                           ) ,
                                ft.DataRow([ft.DataCell(ft.Text("B")) , ft.DataCell(ft.Text("2"))] ,
                                           on_select_changed = lambda e: [clear_chk(e) , e.control.__setattr__("selected" , True) if e.control.selected 
== False else e.control.__setattr__("selected" , False) , page.update()]
                                           ) ,
                                ft.DataRow([ft.DataCell(ft.Text("C")) , ft.DataCell(ft.Text("3"))] ,
                                           on_select_changed = lambda e: [clear_chk(e) , e.control.__setattr__("selected" , True) if e.control.selected 
== False else e.control.__setattr__("selected" , False) , page.update()]
                                           )
                                ]
                        )

    page.add(table)

ft.app(target = main)

Any better idea?
Thank you
