// This function accomodates embedded tables, The parameters are: 
// T obj: an object of the class to be applied to table 
// tablenum: The number of the table being sought out
// numofFuncs: the number of mutator functions being passed in
// f[] an array of function pointers containing pointers to the mutator functions
// sin an input file stream of the Html file
// numargs: the number of arguments that will pinpoint the target table's location 
// if it is an embedded table (a table within a bunch of other tables)
// NOTE: if the Table is not embedded, numargs should be set to zero and nothing should follow it
