From the API I assume you are using the AutomaticSpanningDataProvider which automatically spans cells based on their value. Actually if you read the javadoc of that class, you should notice that your use case is not supported out of the box, as you want the auto span in the first column, but additional logic in the second column that performs auto spanning based on the spanning in the first column.

That said, instead of using the AutomaticSpanningDataProvider you need to implement a custom ISpanningDataProvider that fullfills your requirements.
