I think you recently updated your node with additional information. It is helpful if you clearly annotate any updates. For example, include a header like UPDATE.

When your file has no header row, Data::Table will create default column names in this format, 

col1, col2, col3, etc.

The error you are now getting, 

Invalid column col9Unknown column col9 at /root/perl5/lib/perl5/Data/T
+able.pm line 1794.
        Data::Table::group('Data::Table=HASH(0x15e84c0)', 'ARRAY(0xff0
+300)') called at test_table.pl line 13

suggests that there are fewer than 9 columns in your input file.
