title: JavaFX 2 Automatic Column Width
body: <p>I have a JavaFX 2 table that is displaying contact details for people, lets imagine there are three columns: first name, last name and email address. When my application starts it populates the table with several rows of data about the people already in the system.</p>
  
  <p>The problem is that the column widths are all the same. Most of the time the first and last name is displayed in full but the email address is getting clipped. The user can double click the divider in the header to resize the column but that will become tedious quickly. </p>
  
  <p>Once the table has been pre-populated I would like to programatically resize all the columns to display the data they contain but I can't figure out how to achieve this. I can see that I can call <code>col.setPrefWidth(x)</code> but that doesn't really help as I would have to guess the width.</p>
