Hi @AnnMarieW, I tried your solution (I am using Dash R) for the style of the cell but it did not work. It actually gave every cell a blue border and after clicking on a cell it still was pink. I might switch to Python in the future and try it again.
I am aware that there are other topics (Remove or change hotpink selection from Datatable) regarding this issue, but nothing there was really helpful for me.
I hoped there might be some way to do this with a css file in the assets folder.
Secondly, based on the callback structure I already have I would like to avoid adding another one. So is the callback the only way to highlight a complete row based on the active cell?
