Hi Bikramjit,
I am not able to see any attachment. But as far as I understand your issue, I suggest you use the HTML mode for identifying the table. There is an X-path of each and every element on a webpage. You can uniquely identify the X-path and use it to get your table. Post identifying, use the Read stage with 'Get Table' option to retrieve the table into a collection.
This method worked well for me.
