use backgroundworker progresschanged for using datatable

DataTable tb = new DataTable();
        // Assuming you have initialized the DataTable and TableCollection
        
        // Start the stopwatch
        Stopwatch stopwatch = new Stopwatch();
        stopwatch.Start();
        
        // Perform data processing (loading or equalizing)
        // Example: tb = dt.Tables["TableName"].Copy();
        
        // Stop the stopwatch
        stopwatch.Stop();
        
        // Calculate elapsed time
        TimeSpan elapsedTime = stopwatch.Elapsed;
        
        // Display progress bar and/or elapsed time
        Console.WriteLine("Elapsed Time: " + elapsedTime);
        
        // Optionally, update a progress bar (if using a GUI application)
        // Example:
        // progressBar.Value = 100; // Set progress to 100% when done
