Hi Harsh,
Greetings from Syncfusion.
Table header is allowed to have header with space. If you are importing data from a collection and creating a table,
DisplayNameAttribute may fulfill your requirement.
If this is not your case, kindly share us the sample to reproduce your scenario or let us know the details like: from where are you importing data to Excel table. This would be helpful for us to analyze further and provide prompt solution at the earliest.
Regards,
Shamini
