Answer 1

The answers above I think are pretty good. But let me give you a advice.

1) In ExtJS 4.x it is recommended to use Ext.ComponentQuery`s methods instead of Ext.getCmp()

2) To hide/show columns of the grid you can use following code

Ext.ComponentQuery.query('grid gridcolumn[dataIndex^="service"]')[0].hide()

or to show

Ext.ComponentQuery.query('grid gridcolumn[dataIndex^="service"]')[0].show()

It should resolve hiding/showing any column in a grid.

Here grid is your grid , it maybe id or xtype etc.
