Freezing of table columns and rows & / or visuals

Dear Team ,

Part 1)
There are various times when the table visual used has data which is so long (height wise) that it exceeds page .
Now if we are able to freeze column headers and last row i.e of total .
Then it would be much insightful to user to keep track of which data he is looking into when he scrolls down the page .

Part 2 )
Why only we should restrict our self to columns and rows .
Why can't we have some visuals which can be freezed .
For eg there is a card visual which shows the summation amont of sales and a date slicer ,
Why should the user again and again scroll on top of the page to find these visuals . instead if we have these visuals floating it will be much user friendly and a great feature too.
