datagrid - column appearance regarding parameter

[jaimi]

Is there a way to show or hide columns within a datagrid depending on a parameter? How to do that?

In the following sample I want to deal with that depending on the value of variable vPAR

sample:
$(function(){

 var vPAR = $('#vPAR').val();
 //alert(vPAR);

 $('#edgFirma').edatagrid({
  title : 'Firma',
  iconCls:'icon-firma',
  width:'100%', 
  height:'auto',
  collapsible : 'true',

  columns:[[ 
    {field:'OLT20A004T_KEY',title:'MandantKey',width:130,sortable:'true',hidden:'true'} 
    ,{field:'OLT20A006T_KEY',title:'AdressKey' ,width:130,sortable:'true',hidden:'true'} // if vPAR == 1 the column should be shown
   ,{field:'OLT20A015T_KEY',title:'QuelleKey' ,width:130,sortable:'true',hidden:'true'}
   ,{field:'OLT00L001T_KEY',title:'LandKey'   ,width:130,sortable:'true',hidden:'true'}
   ,{field:'PMA_NAME',title:'Mandant',width:150,sortable:'true',hidden:'true'
     ,editor:{ type:'textbox'
              ,options:{ required:true
                     ,disabled:true
                     ,prompt:'Mandant...'
                     ,missingMessage: 'Geben Sie den Mandanten ein.'
                  }
          }//editor
   }

You can set the 'showHeader' property to display or hide the column header.
