I am trying to use the column visibility property inside columns in an extendedDataTable but the columns I set as visibility=false also show in the table. The same propoerty works fine in a dataTable.
I'd like to know if there's a way to make this work for an extendedDataTable or if theres some other way to keep some columns hidden when the table first loads and then make them visible later using the column drop down list thats provided by the extendedDataTable.
