title: Table does not show all columns in javafx
body: <p>If I run the program then the only column that will be filled in the table will be the "description" column. Still, if I click on the row then it shows me all the details that should be shown in the table.</p>
  
  <p>Here is the source code that I have written:

  <p>I have tried working along examples I have found but I don't see the issue in my code.</p>
  
  <p>Can anyone help me by telling me what I have done wrong? <code></code></p>
