Not really all necessary...
You would need to 
a) replace the datatable-renderer (he is responsible for the
column-header-rendering)
b) create the column-header-component...

Subject: Re: Simplifying column expression

Unless you're using some sort of substitution technology like
facelets, it probably won't be trivial.   You'll need to subclass
UIColumn to create MyColumn, and then either read the
<my:columnheader> tag in as a "header" facet, or have the
<my:columnheader> component create a header facet on its parent
UIColumn on creation.  At least, that's my understanding of the
situation.
