Editable DataTable, save input without pressing 'enter'

🎛️ Dash Dash Python
#1

Hi all,

When a user input a value in an editable DataTable cell, he or she should press ‘enter’ key to save this value. If the user do not press ‘enter’, but for example click outside of the table, the input is not saved and cell value comes back to previous value.

I find it not user friendly at all as usual html inputs and forms have a different behavior (i.e. inputs are saved on focus out, while ‘enter’ usually is reserved to send form as post request).

Is there any way to change this behavior ? It is a small detail but it has a great impact (in my app) on user experience.

I think you can build a callback to do that using this:

@app.callback(Output('your_table', 'data'),
               [Input("your_table", "data_previous"),
                State("your_table", 'data')],
)
def update_table(last, new):

    return new

It should trigger the callback each time the table is modiffy and taking the data as state and returning it as output should do the trick, I hope :thinking:
