Hello,
This table will be used to illustrate Pascal's triangle. I manage to color
the cell (2,0) but I would also like to color the cells (2,1) and (3,1). Is
it possible ?
Thank you
Fabrice

   align = "middle",

   align = "middle",
   style = "type",
   background = "color",
   backgroundcolor = "peachpuff",
