body: <p>I have a table layout which is as simple as <a href="https://developer.android.com/guide/topics/ui/layout/grid.html#example" rel="nofollow noreferrer">this one</a>. </p>
  
  <p>What I need is to allowed end user to click each cell of the table, and do something on each cell. </p>
  
  <p>But, it seems android <strong>table layout</strong> only support <strong>row</strong> based on click event, no <strong>cell</strong> based on click event. How to get rid of this? </p>
