Remarks

The subtypes of Cell are:

Type	Description
EntryCell	A Cell with a label and a single line text entry field.
SwitchCell	A Cell with a label and an on/off switch.
TextCell	A Cell with primary and secondary text.
ImageCell	A TextCell that also includes an image.
ViewCell	A Cell containing a developer-defined View.

The various subclasses are shown in the following image:

Content = new TableView
{
    Root = new TableRoot ("Table Title")
    {
        new TableSection("Section 1 Title")
        {
            new TextCell
            {
