Add button to default D7 view Is there a way to add a selection button or a check box to the display of a default view? I am hoping to catch the node information of the selected row into a bucket or into a container. Below is the screen shot of my default view, I need to add the button or check box at the end of the 'Treatment' column. I have little understanding about the hook_views_default_views_alter(hoping that its implementation is relevant in this case) but not sure how a button could be added using it. Let me know if the question needs more clarification or any additional information is required. 

Thanks
See this drupal.org documentation page called How to add a column with dynamically generated action buttons in a View. hook_views_default_views_alter has essentially nothing to do with this task. Optionally an easier path is like Rules with Views Bulk Operations if you can live with like a checkbox per row, and a dropdown for the operation selection.

The more custom a look, or outside of Drupal's default behavior you deviate. The more work you have to do.
