Problem 2161. Let's get back to school, and create multiplication tables

For a given range, create multiplication tables. (start is always < endno)

Example

 start = 17
 endno = 19

Then,

 table = 
  [ 17    18    19
    34    36    38
    51    54    57
    68    72    76
    85    90    95
   102   108   114
   119   126   133
   136   144   152
   153   162   171
   170   180   190 ]
