Discussion
The <TBL>.FIELD_INFO_DUMP() method returns a CR-LF delimited string of information (such as field name, type, and size) about a table. Note: The <TBL>.FIELD_INFO_DUMP() method has the same functionality as TABLE.EXTERNAL_FIELD_INFO_GET(), except that the latter takes a table name instead of a table pointer.

tbl = table.open("customer")
