consider a list of lists 

{
{{1, 1}}, {{1, 2}}, {{1, 3}}, 
{{2, 1}}, {{2, 2}}, {{2, 3}}, 
{{3, 1}}, {{3, 2}}, {{3, 3}}
}

Now pad a string or letter to the end of the each list within the list
so u get...

{{1, 1},string}, {{1, 2}, string}, {{1, 3}, string}

 or sign

{{1, 1},-}, {{1, 2},-}, {{1, 3},-}

thanks in advance 

sean
