Code-golf: Output multiplication table to the Console

Answer 1

Ruby — 47 chars

puts (a=1..9).map{|i|a.map{|j|"%2d"%(j*i)}*" "}

Output

 1  2  3  4  5  6  7  8  9
 2  4  6  8 10 12 14 16 18
 3  6  9 12 15 18 21 24 27
 4  8 12 16 20 24 28 32 36
 5 10 15 20 25 30 35 40 45
 6 12 18 24 30 36 42 48 54
 7 14 21 28 35 42 49 56 63
 8 16 24 32 40 48 56 64 72
 9 18 27 36 45 54 63 72 81

(If we ignore spacing, it becomes 39: puts (a=1..9).map{|i|a.map{|j|j*i}*" "} And anyway, I feel like there's a bit of room for improvement with the wordy map stuff.)
