title: Can I add an HTML-style tooltip to a Dojo DataGrid?
body: <p>I want to add a tooltip to certain cells of a dojo DataGrid, but I don't want to use dojo tooltips. I want to use HTML tooltips so they have a consistent look-and-feel as the tooltips on my buttons. </p>
  
  <p>In a Dojo Tree, there is a tooltip attribute that does exactly this. Is there a way to do this for DataGrids?</p>
