I am trying some programs on csv files. By searching I saw this "Data::Table". I copied the example in the page given. but its showing an error.

Later I came to know that it need column names. Without column names how can I use this. Because the csv file I am using is auto-generated and does not contains any names in the top of the file. I have permissions only to read the files.

So as per module page

 
table Data::Table::fromCSV ($name, $includeHeader = 1, $header = ["col
+1", ... ])
create a table from a CSV file. return a table object. $name: the CSV 
+file name. $includeHeader: 0 or 1 to ignore/interpret the first line 
+in the file as column names, If it is set to 0, the array in $header 
+is used. If $header is not supplied, the default column names are "co
+l1", "col2", ...
