I expect that table visualization for more than one splits，can be collapsed and expanded!

If there is more than one splits and have many many data, the table view will too height. If you want to find the data you are interested in, you have to scroll to long. so, i expect table visualization's left gutter can be collapsed and expanded, just like tree node view!

In the use-case you described you could just filter to the one dimension-value you need.
