Can I create column names in a gallery table dynamically from a JSON response?

I have to create a table with some edit/delete functionality per row so I'm using a gallery table as opposed to a data table. Our plan is to create a REST API layer we'll make calls to and get a JSON response back. Is it possible to get the column names sent by the API and create the column names from that? The tutorials I've watched on creating a gallery table use hard coded column names and directly connect to their data source (usually a table). We'll be going through an API and hopefully mapping the data to the table (columns and rows). Is this possible in a PowerApps gallery table? Or will I have to just hard code the columns and column names for each of the 9 or 10 different tables we plan on having?
