Datatable - Retain values for daily run

[palindrome (Nitin Safaya)]

To avoid repeat.
First create a new excel/csv file.
Then you ll need to use new datatable (with View column) to append the data to excel/csv and clear the same datatable after each append activity.

To avoid headers in consecutive runs:
check if the new file exists, if yes use append activity. if no, create file with headers.
