Proportional table column spacing upon resizeStack - how to

[Eric Chatonet]

Hi Mark,

Here is another approach using a function that respects the first  
column and distributes x other columns according to the width of the  
field:

on resizestack pNewWidth,pNewHeight,pOldWIdth,pOldHeight
  local tRect,tNumOfColumns
  -----
   put the rect of fld "Table" into tRect
   put pNewWidth - 4 into item 3 of tRect
   set the rect of fld "Table" to tRect
   -----
   put <integer> into tNumOfColumns -- columns total wanted
   set the tabStops of fld "Table" to NewTabStops(the tabStops of fld  
"Table", tNumOfColumns,the width of fld "Table") --
end resizestack
-----------------------------------------------------
function NewTabStops pTabStops, pNumOfColumns,pFldWidth
   return item 1 of pTabStops & comma & item 1 of pTabStops + round 
((pFldWidth - item 1 of pTabStops) / (pNumOfColumns - 1))
end NewTabStops

There are so many ways to achieve the goal with Rev :-)

Best regards from Paris,
Eric Chatonet.
