Solution:
<lang groovy>def printMultTable = { size = 12 ->
assert size > 1
// factor1 line
print ' |'; (1..size).each { f1 -> printf('%4d', f1) }; println()
// dividing line
print '--+'; (1..size).each { printf('----', it) }; println()
// factor2 result lines
(1..size).each { f2 ->
printf('%2d|', f2)
(1..<f2).each{ print ' ' }
(f2..size).each{ f1 -> printf('%4d', f1*f2) }
println ''
}
}
printMultTable()</lang>
Output:
