Add a simple row to JavaFx tableView
<p>I am quite new to <code>TableView</code> and customizing it in JavaFx. I've gone through many tutorial, I've understood some but stucked in adding rows into my table. 
For example, I have a table called <code>Table1</code>. According to my understanding I can create columns <code>ArrayList</code> and: </p>

<pre><code>for (int i = 0; i &lt;= columnlist.size() - 1; i++) {
    TableView col = new TableView(columnlist.get(i));
    Table1.getColumns().add(col);
}
</code></pre>

<p>Now how can I add a row to this? I will appreciate if you can give me a very simple example as I have gone through other examples but they were too complex :)  </p>
