In a Table, you are able to render the cells value as a URL and use the cells value as input for the URL. It is currently impossible to use the value from another column as the input for the URL.
For example:
You have a table in which you show your Christmas Wishlist. It shows the product, the price, and the URL to where you can buy it. It would be nice to be able to just show the product and the price and access the URL by clicking on the product, instead of having to add the URL as a separate column.
