Dynamically changing column visibility on DataTable during ajax refresh

Hi all,

Is there a way to change the visibility of one or more columns of a
DataTable during an ajax refresh?

The only way I've found so far is to create a new list of columns and
replace the DataTable but this is a bit cumbersome compared to simply
writing ajaxRequestTarget.add(dataTable);

Thanks Sven.

I was looking into implementing a isColumnVisible(int columnIndex) method,
and your suggestion makes this quite easy.

Hi,

you can alter the list of columns you have passed to the DataTable 
constructor:

     new DataTable(id, columns, ...);

     onConfigure() {
         columns.clear();
         columns.addAll(...);
     }

     onClick() {
         target.add(dataTable);
     }

Regards
Sven
