How to edit Table data ?

Hi Wix teams,

I just created a table via "Add Button" > "Lists and Grids", and selected this table : https://i.ibb.co/wyrWNY1/Capture-d-e-cran-2019-07-04-a-16-09-40.jpg (sorry for the link, wix images upload don't work on the forum).

What's the way to edit the data of this table ? Couldn't find any way !

I also saw weird column fields types, like "amenities" which just puts columns in bold, "deluxe" which puts some ticks. Didn't found any documentation about it.

Thanks a lot for your help !
