inserttable() method allows to quickly insert large blocks of data in a table: it inserts the whole values list into the given table. The list is a list of tuples/lists that define the values for each inserted row. The rows values may contain string, integer, long or double (real) values. Be very careful: this method does not typecheck the fields according to the table definition; it just look whether or not it knows how to handle such types.
