Adding constant column to p:table with <p:columns>

[MechanicalWolf]

Hi!
i need to make a table that has unknown count of columns (the new feature <p:columns> is good for it.
The problem is : i need to add one constant column to the table, where will be displayed the delete row button. is there any chance to add a column to dynamic columns?

You can add the constant one programmatically why not, also we can improvide p:dataTable to use p:columns and p:column together.
