+# In this scenario, TiDB Lightning will ignore the CSV header to avoid errors and import the data directly in the order of the columns in the target table.
+# Therefore, if the columns are not in the same order, you need to manually adjust the order of the columns in the CSV file to be consistent with that in the target table before importing; otherwise data discrepancies might occur.
