Cartesian product exception with ANSI-89 Syntax
when i use LineageRunner to analyze a sql string like "select a.* from table a,table  b "   it throws a  SQLLineageException:
SQLLineageException: An Identifier is expected, got IdentifierList[value:  a, table] instead 
So how can i deal with that exception? 

`from sqllineage.runner  import *
LineageRunner("select a.* from table1 a, table2 b").target_tables`
