Hi Houssam Smail,
You need to manually add those csv fieldInfo based on your schema and loaded as fieldInfos inside of FeatureTable Widget. And you probably need to setup proxy to make sure the requests pass the CORS, or put your csv file and application in the same web domain.

Hope this can provide you some inspiration to do.
thank you 1 million times
