title: JavaFx: TreeTableCell border css
body: <p>I am trying to style my cells in a <code>TreeTableView</code> but something I cannot figure out how to implement.</p>
  
  <p>I want different colors for the right-left border and for the top-bottom, but that way the right-left(those lines which separate the columns) to be on the "top". I will show it with an image what I mean.</p>

  <p>I want that the red line to be continuous rather than the blue one.
  As you can see the red lines are interrupted by the blue ones.</p>
  
  <p>Here is the code part which is relevant:</p>
  
  <pre><code>.tree-table-cell{
      -fx-border-width: 0 5 1 0;
      -fx-border-color: transparent red blue transparent;
  }
  </code></pre>
  
  <p>How can I achieve that the red lines to be continuous and the blue ones to be "dashed"?</p>
