Hi Rohit,
For scraping the website for information, you are best to look at the link i sent previously. This will take you through using either the Download tool/Python functionality to scrape information from a webpage. This is a very useful part of Alteryx.
There is also a great source here on using Python to scrape a table from a webpage: https://community.alteryx.com/t5/Engine-Works/Web-Scraping-will-it-Alteryx/ba-p/429475
As far as displaying a website in Designer, as far as I am aware, this is not possible dynamically. The website has to be a hardcoded site, and you cannot pre-define login details for it to login to the site when the workflow is opened.
Hope this helps,
TheOC
