    The check for "totalSize <= 0"  is there to terminate the loop early, 
incases where these are two tables that add up to <= 0.
    
    And the check for negative valaues is covered here 
    
    if (tableSize <= 0) {
              fallbackToEqualProportions = true;
              break;
            }
