David,
It finally occured to me: you must assign an ID to the child control.
Nothing will automatically assign one to the control.
Previous thoughts:
You may need to call EnsureChildControls at some point after adding
the textboxes to the cell since the textboxes aren't a component/property
of the cells.
I played around with createing 'table-maker' controls in VB.Net a while back
so I can provide some code if needed..
