Error create table programmatically "Table Body has X rows but 0 are expected"

[FMorales]

Hi, 

I am trying to create a report that includes a table dynamically generated, I will not use the viewer control, just I would like to generate the table from a DataTable but after compose the with the method "GenerateTable" and save the file I always get the error "An error has occurred while processing Table 'xxxx':
Table Body has 2 rows but 0 are expected"

What is wrong?, any help would be appreciated.

I finally realized that I miss to create groups in the rows and this seems to be the reason for the problem.

This code update generates the table.
