Create a table with dropdown list on grafana

hello in my project I have to create a specific dashboard with a set of ergonomic criteria above all. I explain my need: in fact I created a table with main elements and I need to make a drop-down list as in the photo but do not happen or I imagined to create two dashbaord with links if if I press on “DEVLOPEMRNT GROUPE” I have to go to another dashboard which will contain “CONTACT” and “RENDEZ -VOUS” but also I cannot manage to apply a link by element (I find the possibility of applied one url per column and not per cell)
Another thing please for the blue color of the first line of the table I can not change it as the shades of gray as in the photo thank you very much I am in a hurry and it is urgent thank you again
