Dash Python
1

Hi everyone,
I have prepared a dashboard. Where I have a dash datatable.
df is the dataframe from excel file

html.Div([
            
                                          dash_table.DataTable(
                                                  id='data-table',
                                                  data=df.to_dict('records'),
                                                  columns=[{'id': c, 'name':c} for c in columns],
                                                  filter_action="native",
                                                  fixed_rows = {'headers': True},
                                                  style_cell={'width': '200px', 'textAlign': 'center'},
                                                  style_table={'overflowX': 'auto','overflowY':'auto','maxHeight': '400px','minwidth':'100%','font-family':'Calibri'},
                                                  style_header={
                                                            'backgroundColor':  'rgb(52,98,145)',
                                                            'textAlign':'center',
                                                            'color':'white',
                                                            'font-family':'Calibri'
            
                                                                }
                                                  ),
                                          html.Div([
                                                              html.Button('Save', id='save-button'),
                                                              html.P(id='editable-table-hidden', style={'display':'none'}),
                                                              html.P(id='save-button-hidden', style={'display':'none'}),
                                                         ], className='row')

And the callback is-

@app.callback(Output('save-button-hidden', 'children'),
                          [Input('save-button', 'n_clicks')])
def clicks(n_clicks):
    if n_clicks > 0:
        df.to_csv('df.csv', index=False, encoding='utf-8')

How to download the data from the table after using Filter.
I am using the above code but the data that is being downloaded is the df. I want the data that is in the datatable to be downloaded after applying the filter.

How to do the same ? Kinldy help.
