Add dynamic section to a table

[#1]

I have a complex form that requires a signature box. As the form may require multiple signatures, I structured a small table (4 rows); now I need to repeat those rows using the instance manager. The four row are in a section, so it is the section that I need to repeat.

I am using:

Table1.Section1.addInstance(1);

But this does not work. Any help would be appreciated.
