Is there any pointers to change the markup header of a column or propertyColumn ?

[andre seame]

Hello,


In DataTableFilterToolbarPag, we use columns.add(new PropertyColumn<Contact, 
String> ...


I would like to modify the content of the header of this column.


Must I do "replace the header component of the header of column" ? But how to 
do that?


Must i my own column objects? I imlagine that the header (th) is defined by the 
column. But how to do that?


Thanks,

PHL.
