When a question is displayed directly in Metabase the column headers lock in place, allowing the user to scroll without losing the meaning of the column. When the same question result (row display) is shown in a dashboard, however, the column headers are not segregated from the display of the rows, but are part of it. Thus, if you scroll down too far, the column headers go out of the screen viewing area. Having an option to lock the column headers in a dashboard card would be very helpful.
Hi @plg6
There's a request for that:
