title: APEX Tabular Form with [row selector]: How to set value of column in selected rows on submit
body: <p>I have a tabular form that displays all requests submitted for processing. Submitters have the opportunity to cancel requests at any time. I would like this to be accomplished by simply checking the row selector checkbox of the row(s) that should be cancelled and clicking submit. </p>
  
  <p>Ok... What I am trying to create is a tabular form that, when the [row selector] checkbox is checked and the form is submitted, the value in the 'Status' column of the row is set as 'Cancelled'.</p>
  
  <p>Since the [row selector] checkboxes exist, my guess is there is probably a built in process of some sort that identifies the selected rows and runs an action on the selected rows. </p>
  
  <p>Is there a way to tap into this functionality and take the extra step to set the value of the 'Status' column of the row to 'Cancelled'? </p>
