Thanks Mark, but as usual, the idea would not leave me alone, and kept drilling into my subconscious so I made a way to do it. 

on mouseDown pButtonNum
   if pButtonNum <> 3 then pass mouseDown
   put getClickedColumn(the long id of me) into tClickedColumn
end mouseDown

function getClickedColumn pDGID
   put the mouseControl into tTargetNum
   put the name of tTargetNum into tTargetName
   put the left of pDGID into tLeftMargin
   put item 1 of pDGID mouseLoc into tMouseClick
   put (tMouseClick) - tLeftMargin into tColumnClick
   put the dgProp ["column widths"] of pDGID into tColumnRightEdges
   put the dgHscroll of pDGID into tHscroll
   subtract tHscroll from item 1 of tColumnRightEdges
   
   -- shift all column rights left by hscroll
   repeat with i = 1 to the number of items of tColumnRightEdges
      add item i-1 of tColumnRightEdges to item i of tColumnRightEdges
   end repeat
      
   -- find which column the mouse was clicked in
   repeat with i = 1 to the number of items of tColumnRightEdges
      if item i of tColumnRightEdges > tColumnClick then exit repeat
   end repeat
   
   put the dgProp ["columns"] of pDGID into tColumnNames
   put line i of tColumnNames into tClickedColumn
   return tClickedColumn
end getClickedColumn
