Fast Hidden column

If you want hidden a column set width to 0px in structure

ex:

Structur = [ { field:'id', name:'Id',width:'0px'}, { field:'nome', name:'Nome',width:'200px'},......

!IMPORTANT

In Firefox >= 8 you must add this code in your css

/* firefox td width 0px*/

.gridxCell[style*="width: 0px;"]{ margin:0px; padding:0px; border:0px;

}
