I am about done with this control, but here is one for the future...
Symbols are practically undocumented, I suppose it's because they highlight the fact that the control gives the developer no control over the current location in a document:
What page am I on?
How much page do I have left?
Anyway, here is another problem:
This works
sec1.Paragraphs.Add(new Text("#$NP"));
This doesn't
cell1.Paragraphs.Add(new Text("#$NP"));
