title: Remove spaces/lines between rows in GXT Grid
body: <p><img src="https://i.stack.imgur.com/HAAPn.jpg" alt="My problem"></p>
  
  <p>My goal is to create a solid line between certain columns of a Grid.  To accomplish this, I've done the following to the appropriate column:</p>
  
  <pre><code>ColumnConfig colConfig = new ColumnConfig("myID", "My Col Title", 50);
  colConfig.setStyle("border-right:solid medium black;");
  </code></pre>
  
  <p>As you can see from the attached picture, the rows seem to have spaces between them that is preventing my column border from being a solid line going down.  Can anyone help with either eliminating these lines between rows, or some alternative to accomplish my goal?</p>
  
  <p>I see there is a method provided on the Grid type itself to turn on/off column lines:</p>
  
  <pre><code>grid.setColumnLines(false);
  </code></pre>
  
  <p>But I don't see anything for rows.  I also don't know whether even for columns that method is hiding the lines or actually removing them - I suspect the former.</p>
  
  <p>Thanks in advance for any and all answers.</p>
