title: RowSpan and ColumnSpan in Xamarin.Forms
body: <p>Is there anyone out there who can explain to me how <code>RowSpan</code> and <code>ColumnSpan</code> work in <code>Xamarin.Forms</code>?<br />
  The parameters right, left, top, and bottom are a little bit confusing.</p>
  <p>Let's use this code snippet for <code>RowSpan</code>:</p>
  <pre><code>grid.Children.Add(new Label
  {
     Text = &quot;Span two rows (or more if you want)&quot;,
     TextColor = Color.Yellow,
     BackgroundColor = Color.Navy,
     XAlign = TextAlignment.Center,
     YAlign = TextAlignment.Center
  }, 2, 3, 1, 3);
  </code></pre>
  <p>What do the numbers 2, 3, 1, 3 mean in terms of columns and rows here?<br />
  This is for a grid with four rows and three columns.</p>
