Merging Dynamic Cells in xlsx report.

[chalapathirs]

Hai,
I am trying to generate report in excel format. I am trying to merge the cells dynamically (i.e) inside {{#each}}. Unfortunately I am not succeeded and getting the following error "We're sorry, we couldn't open your workbook. It's possibly corrupt or using a file format that's not supported."

I am not sure what I am missing.

Please help me get this resolved.

Here is the demo for cells merging.

To troubleshoot the errors it is recommended to download the xlsx. Unzip it and compare the xml files with a working xlsx created directly in excel.
It is tedious but the closest you can get when analyzing the error.
