Describe the issue:

When selecting an element in DataExplorer, I sometimes want to know which row that element is on.
I'm aware of the "Select row"-feature, but it doesn't work when I select/highlight multiple elements to view their row range.

Expected or desired behavior:

I'd prefer to have both the rows(s) and columns(s) of the selected elements in the DataExplorer highlighted when selecting elements.

Start at the DataExplorer selection behavior described in the issue and compare it with the existing "Select row" feature. Verify how multi-element selections expose row and column ranges, then confirm completion when both corresponding rows and columns are highlighted.
