title: How to set and get the cell value of JavaFX Table like swing JTable
body: <p>I am new to <code>JavaFX</code> and would like to know how to set and get the cell value of <code>JavaFX</code> Table like <code>Swing</code> <code>JTable</code>. i.e. an alternative of <code>setValueAt()</code> &amp; <code>getValueAt</code> of <code>Swing</code> <code>JTable</code> in <code>JavaFX</code> Table. </p>
  
  <pre><code>//would like to get the index of column by Name    
  int index_RunnableQueueItem = tableQueue.getColumns().indexOf("RunnableQueueItem");
  //would like to get the selected row
  int row = tableQueue.getSelectionModel().getSelectedIndex();
  if (index_RunnableQueueItem != -1 &amp;&amp; row != -1) {
  // would like to get the value at index of row and column.
  
  //Update that value and set back to cell. 
  
  }     
  </code></pre>
