Multi column scrolling with checkbox

[rgould8 at aol.com]

Can anyone tell me if there's a way to create a 2 column text field, where the user can have editable text in the left column, and in the right column have a checkbox?  (So that the checkboxes all line up with the text and scroll with the text if the vertical scrollbar is used).  Special bonus if I can have the rows with alternating colored backgrounds.
