  When state saving is enabled, the state that is loaded will be the one that "wins". State saving will override the initialisation settings - that's the whole point of state saving .

  So to allow your class to work, you'd need to clear the saved state.

  OK, i understand that, it is logical

  But, I bet i am not the only one with such a case. And for this kind of situations, is there really no way like saying: ok, save everything, but ignore columns (with some kind of identifier, in my case css class.).

  My case is that i have users who have their roles. And based on permissions set to a role, a column for mass edit (check boxes) is hidden or visible.

  This is pretty much the whole story
  And it is a big decision/tradeoff between usability of datatable save state and being able to set some security based elements inside the table.

  Thx for the answer

  Yes, you can have it ignore columns. The stateSaveParams callback can be used for this. You can have it delete the columns parameter and everything will be saved except the column information.

  Can you post an example?

  For example (with StateSave: true and target column = 1 with visible: false and class="col_to_hide") using:

  "stateSaveParams": function (settings, data) {
  //
  }

  If you want to not state save column visibility you could remove the visible parameter from the columns array of objects in the state object:

  stateSaveParams: function ( settings, data ) {
    for ( var i=0, ien=data.columns.length ; i<ien ; i++ ) {
      delete data.columns[i].visible;
    }
  }
