Hi, all
About Commons CSV [CSV-261](https://issues.apache.org/jira/projects/CSV/issues/CSV-261?filter=allopenissues) Here is a usage scenario that ignores all empty values lines like "，，，\r\n" in the CSV file, This behavior is very useful. So we can consider supporting it in Commons CSV. I have a preliminary implementation, which is to add ignoreEmptyColumnsLines in CSVFormat, and then filter the records which are all empty values in CSVParser. you can review the code in https://issues.apache.org/jira/secure/attachment/13002690/CSV-261-dota17.diff what do everybody think of this ? - Chen Guoping
