title: Setting a tooltip on all table cells in JavaFX
body: <p>My application contains a <code>TableView</code>. Depending on the value of a specific cell in each row, the row style is changed by setting a custom cell factory with <code>setCellFactory</code> for this column. This works fine.</p>
  
  <p>Now I'd like to add a tooltip which is no big deal using <code>setTooltip()</code>. However this tooltip shall be set for <strong>every cell</strong> in the table, not just the column it is specified for. How can I implement this?</p>
