form inside a table

I'm not sure whether I want a form inside a table, or a table inside a 
form.  A table something like:


field1      field2       field3
data        more data    even more data
second row  data         some data
[]          []           []


the third row is blank.  How could I add a column of submit buttons which 
"listen" only to their row?  I see how to create a button for a table:

but how do create a submit button for a row?



thanks,
