DataTable headerColumnGroup prop show unespected warning

[m4rko80]

Hello everyone,
I am using primereact latest versione 10.9.1 and i show many warning when using headerColumnGroup props to show a custom grouped header.
For istance this code display correctly my HTML but with warning:
`
const content = (<>some content</>)
<DataTable
headerColumnGroup={content}
//... more props

`
From types definitions, headerColumnGroup accept React.ReactNode || undefined.

I didn't found when it start to show warning but at the moment i didn't figure out to solve the problem.

If i use this code i dont see any warning but nothign in rendered:
`
const Content = ( ) => <>some content</>
<DataTable
headerColumnGroup={}
//... more props

So, is not something about the content itself but i don't know how to fix it.

Any idea?

Thanks!
