Is it possible to get the clicked cell for a table field, if the table is empty?

Found an interesting behavior.. I was trying to set up a custom control
that keeps track of the current row and column and put the script in the
group, but rawkeyup or rawkeydown messages never reach the group.  I'm
wondering if its because the message is sent to the figmentary popup field
rather than the table field, and that the popup is not part of the group.
But "the target" refers to the table field itself, so i'm not sure thats
whats happening.  Either way.. The following script works when put into a
card or stack, NOT group, and not in the table field itself.  Kinda freaky
that the message is sent, just not to where I expect, despite "the target"
still pointing back at the table field.

on mouseup
  getline
  pass mouseup
end mouseup
on rawkeyup
  getline
  pass rawkeyup
end rawkeyup

command getline
  if the short name of the focusedobject contains "revCell-" then
  put the short name of the focusedobject into tName
  replace "revCell-" with empty in tname
  set the cCol of the target to item 1 of tName
  set the cRow of the target to item 2 of tName
  end if
end getline

I just tried a quick test and tName has the cell row and column.

Reason is, I’d like to move my nested data grid behavior to a script only stack, but it occurs to me this might break the datagrid, since it’s next level behavior is the old data grid behavior button (not sure why that’s still there) then the actual script only datagrid library.
