Report XLSX template dynamic row height

Creating an Order report, product name can use 1 or more lines at the same roiw. I can’t find a way to autommatically adjust the XLSX row height. Is there a way to do it? Indeed, if I adjust the row height at XLSX template, it remains fixed and doesnt resize autommatically when report is launched.

Another question I have is, how to display a TOTAL band (some rows with total values) at the bottom of the last page no matter how many product rows or how many pages are displayed. I only got to display TOTAL band inmediatelly below product lines (i want it at the bottom of page)

Thanks in advance

Giving a try to Jasper, I got to achieve it. But I have a problem with a static Header Image. Will open a new post.
