Hi Richard Are you using '#tree' => TRUE? If so, you can access $form_state['clicked_button']['parents'] which will be an array of the keys of the parent elements. If each row in your table is built as follows: $form['rows'][$row_id]['field1'] = array(...), $form['rows'][$row_id]['field2'] = array(...) etc and you are rendering this as a table using a theme function and element_children to determine the valid values of $row_id (is there any other way?) then your ['clicked_button']['parents'] will contain an array including the final op but also the 'parent' $row_id, this can tell you which button was pressed. Have a look at the quicktabs module for an example.

Actually all buttons in a Drupal form have the name "op" so that you can easily determine which button was pressed in the submit function. i.e. if ($op = 'blah) or switch ($op).
If you are using the Drupal Ahah framework for this then your submit function should handle it. But since all your buttons are titled Remove, what you can do is use $form_state['clicked_button']['#id'] to determine which button was clicked in your submit function. As #id is built of the array key you give the element in the $form variable.
I know that by default they are all named 'op'. This is my problem; I cannot distinguish the buttons by their '#value', because it is always the same. I'm solving this by setting the '#name' to allow me to determine precisely which button was clicked. If I don't set '#name', then *regardless* of which button I press, the 'clicked_button' structure in the $form_state corresponds to the last button of the same '#value' added to the form. Part of the awkwardness here is that HTML doesn't allow you to display some text in a button while having a different value.
