Then I don't understand why you want to end up with 10 records in the nan table. Then I have some more questions:
1. The nan table has 10 records, and you want to only keep the data from one column?
2. You want to add the data from the 10 first records in the xldata into the nan table?
3. What about the remaining 139 records in the xldata table?
