The Kendo TreeList has an incorrect colspan value for the headers when the first column is hidden and the file is exported to Excel.
Dojo:
https://dojo.telerik.com/IFuCutaV/4
The names of the headers are not displayed in the correct positions.
This behavior was originally reported over 4 years ago and has not received significant demand or follow-up from the community since then. Considering this and the availability of a workaround, we are unable to prioritize it over more impactful and widely requested improvements.
If this limitation is still affecting your scenario, please share additional context or use cases. This will help us better assess the severity and reconsider prioritization in the future. Thank you!
