Hi @sunjincheng121, thanks for your reply. I think an example would be
that, for some non-standard CSV files like `a, b , c,`, if the boolean flag
`trailingDelimiter=false`, the file will be parsed with 4 fields; while if
`trailingDelimiter=true`, the file will be parsed with 3 fields, in which the
trailing delimiter `,` is omitted. Further, the trailing delimiter could be set
as another character, e.g., `a, b, c;`.
