sqlite3.OperationalError: no such table: meat

[alpha0067]

hi, i think pysqldf is more powerful library than pandasql.
According to the author's example：
from pysqldf import SQLDF, load_meat, load_births
sqldf = SQLDF(globals())
meat = load_meat()
births = load_births()
print sqldf.execute("SELECT * FROM meat LIMIT 10;").head()
i find the hint that sqlite3.OperationalError: no such table: meat
who can help me?
