How to make tables accessible

The main issue is that if some cells are NOT clickable and others are, then it will be a poor user experience if user tries to click on the cell and nothing happens.

enter image description hereI need some help in writing labels for screen reader. The issue we have is that not all elements within the table are clickable, so how does this work? How can it be made user friendly if user thinks that one item is clickable and then it's not, unless we create a label for every cell?
