I was working the code myself and found another way of individual filling but your way is much cleaner I think. Is there also a way of filling a group of cells (which is not a full column or a full row)? All the cells with type 1 are are already defined and then I need to fill like 60% of the remaining cells with type 3 and the other 40% with type 4. I think I need to add a method to the code which lets me do that but I'm don't have much experience with ruby so I don't know how to do this... Can anybody help me further on this? -- Posted via http://www.ruby-forum.com/.
