Datalinks with table cell sparklines? Feature request or maybe just need a how-to

Hi all, I posted a feature request nearly a year ago and surprised there appears to be minimal interest in it:

I thought it would be common to create a table with thumbnail charts, and then click one to open a dashboard with more relevant details and selectable time ranges. In network monitoring apps and I’m sure in other technical monitoring solutions as well, this concept is called “drilling down” to get more detail.

I use datalinks just fine if the cell content is text, but cell sparklines do nothing when I add an override for Datalinks.and try to click the cell.

Maybe I’m doing something wrong, or maybe it’s just not supported, and how do other people implement this type of functionality in Grafana? I don’t want to use a hack like an extra column next to the sparkline column because we have multiple columns of sparklines and screen real estate is precious.

Thanks in advance for any pointers or help.
