When I run Mail Merge on the modified document, it is moving the labels slightly down,
(may be because of the TableStart and TableEnd tags that I have added)
so in the output document bottom margin is less than the original document.
I have attached both IN and OUT documents for your reference.
You will also notice the small gap between labels.
Is there any way I can maintain the same margins and same labels’ coordinates as I have in the original document.
Thank you for additional information. Gaps between each cell is added because there are two paragraphs between each next cell (paragraphs with TableStart and TableEnd).
Anyway, I think the best template design for such purposes is the template I suggested you in my very first answer in this thread, i.e. template, like in the following forum thread: https://forum.aspose.com/t/94886
I think, you should be already familiar with the technique of building templates. So there should not be any problems to build the same template.
Best regards
