How to manage selection of table row in perspective

I have requirements to display Dropdown component in table row.
I am having two issues:

  1. when row is selected then I am not able to select item from dropdown. If table having more rows then directly clicking on dropdown of unselected rows then it works. Once rows gets selected then selection of item from dropdown doesn’t work at all.

  2. I would like to have dropdown read only but when user clicks on cell containing dropdown, it goes editable mode and user can edit the item. Instead, i would like to have it read only.

Could you please let me know how to resolved these issues.
