   This function was ripped off directly from somewhere in skia. It is
   inefficient and so, should be avoided for large data sets.
 
   Args:
     data (list): A list of lists of strings containing the data to tabulate. It
       is expected to be rectangular.
 
   Returns: A multi-line string containing the data arranged in a tabular manner.
