How to do responsive table layout?

Hello,

First of all, can you precise the context or better provide an Url link to allow us to better understand the situation?
But in a general way, you can add Css like this, follow me step by step :
- Have a look on this Documentation to see how to add your custom Css command
- You have to use the "@media" command to have css commands active only for specific screen dimensions
Example :

@media only screen and (max-width: 600px) {
        body {
            // Your command Css
        }
}
