I think I worked out how to do it, but still I don't understand why the 2
outouts are different, and only second is correct.

#! /usr/bin/ruby

#table acces function
def ta(table,row,column,value)
  r=table[row];  r[column]=value
end

#### create 2 dimensional array #############
t=Array.new  
for x in 0..9
  row=Array.new
  for y in 0..9
    row[y]=x+1*y+1
  end#for
  t<<row
end#for
#######################################
puts t.inspect

#create multiplication table
for x in 0..9
  for y in 0..9
    ta(t,x,y,x+1*y+1)
  end
end

puts t.inspect
