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.
