Update not the header in p:dataTable - only rows (content)

[vished]

Hello,

I want to have following:
pe:blockUi for filtering my datatable content.
The filter is in my <f:facet name="header">

So now I want to update only the columns in my datatable.
How can I do this?

Thank you very much for your help
Best regards
