Please update: All the code are not usable anymore

Hi, Adriano

Can you update the code to the current version of Dash? I tried to learn Dash but the code can't run, especially for data table.

Hello Sir,

I also have the same request as @KangboLu, and I have been able to update your code to the latest version with some minor tweaks.

Shall I send a pull request?
