Increasing space size between table cells - ios

Question

I have made a UITableViewController, and in it, have programmatically added in cells. I have used snippet code directly off of Microsoft's website on how to create a table using Xamarin: https://learn.microsoft.com/en-us/xamarin/ios/user-interface/controls/tables/populating-a-table-with-data
The only problem is that the code used produces a table which, when you add cells to, creates a spacer between each subsequent cell, of increasing size:
And my storyboard of the UITableViewController looks normal, and it contains no constraints or spacing:
Does anyone have any idea as to why this error might be occurring?
To clarify the code used for the source file for the table is:
public class mailSource : UITableViewSource
{
string[] TableItems;
string CellIdentifier = "TableCell";
public mailSource(string[] items)
{
TableItems = items;
}
public override nint RowsInSection(UITableView tableview, nint section)
{
return TableItems.Length;
}
public override UITableViewCell GetCell(UITableView tableView, NSIndexPath indexPath)
{
UITableViewCell cell = tableView.DequeueReusableCell(CellIdentifier);
string item = TableItems[indexPath.Row];
if (cell == null)
{ cell = new UITableViewCell(UITableViewCellStyle.Default, CellIdentifier); }
cell.TextLabel.Text = item;
return cell;
}
}
And the code for the view controller is:
public partial class mailTableController : UITableViewController
{
public mailTableController (IntPtr handle) : base (handle)
{
}
public override void ViewDidLoad()
{
base.ViewDidLoad();
table = new UITableView(View.Bounds); // defaults to Plain style
string[] tableItems = new string[] { "Vegetables", "Fruits", "Flower Buds", "Legumes", "Bulbs", "Tubers", "a", "a", "a", "a", "a", "a", "a", "a", "a", "a", "a", "a" };
table.Source = new mailSource(tableItems);
Add(table);
}
}
