Setting colspan for header in Table?

[Ddd-Jw]

I want to do something like the screen shot above, that a header have a colspan of 2. Can't seen to find an easy way of doing it yet.

All helps are appreciated.

Thanks

@Ddd-Jw thank you for sumit discussion. Yes, currently, if you need to merge cells in the header, you can only achieve this through the header template. There are corresponding examples on the official website. If you have a better solution, you can submit a pull request (PR) to us, or share your approach, and we can implement it as well
