Is the column `Action` very important?

Question

Is the column Action very important to being displayed in admin grids? It is actually doing exactly the same thing as "click on selected row" a'm I right ? So if I hide it will it affect anything ?

        if (Mage::getSingleton('admin/session')->isAllowed('sales/order/actions/view')) {
        $this->addColumn('action',
            array(
                'header'    => Mage::helper('sales')->__('Action'),
                'width'     => '50px',
                'type'      => 'action',
                'getter'     => 'getId',
                'actions'   => array(
                    array(
                        'caption' => Mage::helper('sales')->__('View'),
                        'url'     => array('base'=>'*/sales_order/view'),
                        'field'   => 'order_id',
                        'data-column' => 'action',
                    )
                ),
                'filter'    => false,
                'sortable'  => false,
                'index'     => 'stores',
                'is_system' => true,
                'column_css_class'=>'no-display',
                'header_css_class'=>'no-display',
        ));
    }

To make it invisible added two lines:

'column_css_class'=>'no-display',
'header_css_class'=>'no-display',

instead of removing or comment.

Answer 1

Generally, the Action column is not important as long as it is doing the same as clicking on the row. Action tab is added when there are more operations to perform on a row, like in the CMS Pages grid you can see there is an Action column that has preview action. Here both click on row and preview performs different operations.

So you should only remove it if both the operations are the same.

Answer 2

$this->addColumn('action', array(...)) adds the action column in the grid. Yes if you wish to remove you can. You can remove from css, commenting or by removing the whole code.It will not break your grid or will not affect any of code breaking.

But talking from UI point of view since you have the edit form its good to keep the action column so user knows the action and he can navigate there.
