Populating a Table using an Array?

In the process of building a macOS application that will analyse data collected from an on-line database, which can then be used for local analysis. I am a radio hobbyist and want to compare two antennas I have built.

The data is collected into a delimited text file and the contents placed into an Array. I do this by:

@Observable
class DataModel {
var fileName = "No file selected"
var windowTitle = "WSPR Analysis "
var recordArray: [[String]] = []

    }

func readTabDelimitedFile(atPath path: String) -> [[String]] {
  do {
         let fileContent = try String(contentsOfFile: path, encoding: .utf8)
         let lines = fileContent.components(separatedBy: .newlines)
         var parsedData: [[String]] = []
     for line in lines {
       if !line.isEmpty {
       let values = line.components(separatedBy: "\t")
       parsedData.append(values)
    }
}
return parsedData
  } catch {
    print("Error reading file: \(error.localizedDescription)")
    return [[""]]
   }
}

The first row in the array will have the Header names

dataModel.recordArray[0]

While the remaining of the rows contain the data to displayed in the Table cells.

My problem is, I don’t understand how to populate the Table View and have the headers reflect what’s in dataModel.recordArray[0].

Can someone help me ?

This is doing something very similar.

BTW, this forum is for topics related to Swift and its standard library, not about Apple frameworks (SwiftUI, UIKit, etc).

Thanks and my apologies tera.
