SELECT DISTINCTROW MSysObjects.Name, MSysObjects.Type FROM MSysObjects
WHERE MSysObjects.Type=1 AND MSysObjects.Name = [name to check for]

If it does not return anything than you don't have such a table. Note that you might want to check for a query with that name as well:

SELECT DISTINCTROW MSysObjects.Name, MSysObjects.Type FROM MSysObjects
WHERE MSysObjects.Type=5 AND MSysObjects.Name = [name to check for]

Access does not allow table and query have the same name. So you might kill a query by creating a table and seting warnings to off.
