Enhancement

Lightning from v5.0.2 , still can not locate the problem by reporting an error. When importing in csv format and the file name is incorrect, an error is reported table not found in schema, it is recommended to report a complete error: file cant match table

Contributor guide

Research direction
Investigate the error handling around table schema lookup during CSV import in Lightning. Identify where the incomplete error message 'table not found' is generated and trace the code path from file name parsing to schema matching. The goal is to improve the error message to include the filename mismatch.
