Hello. Do you want to merge cell programatically? If you need to merge cells in the template you don't have to use any methods - just merge the cells you need inside bands and the merge will be replicated.

Thanks very much for your answer。

But sometimes，we need to get the number of merged cells according to the children rows。How to solve this situation?

Best regards

For now you have only ability to post-process the document (to run custom logic after document generation). But, we plan to include the logic you describe to next releases.
