    Reconfigure exists on Ext.grid.Panel. I suspect it still exists in EXT 4 for the others as well…

    reconfigure( Ext.data.Store store, [Object] columns ) : void

    Reconfigures the table with a new store/columns. Either the store or the columns can be ommitted if you don’t wish to change them.
    Parameters

    store : Ext.data.Store
    
    (Optional) The new store.
    columns : [Object]
    
    (Optional) An array of column configs
    

    Returns

    void
