How to style pinned column when selecting any row or hover

[devpju]

"I am using the original code from the example on your website (version: v2). I have pinned the action column, and when I select the checkbox of any row, I notice that the background-opacity of the pinned column is quite low, which causes the text behind it to be visible. I also encounter the same issue when hovering over that row. Currently, I don't know how to style it, and I would appreciate any help.
