  <p>A tree can be added into a sheet. To do so, there are two steps which must be done.
    First, the <code>value</code> attribute of the sheet must refer to a method, which return a tree instead of a list.
    Second, to display the tree, use the <code class="language-markup">&lt;tc:columnNode/></code> tag.</p>

  <tc:section label="Column Tree">
    <p>There is a tree in the first column. You can expand and collapse the items.
      The <code class="language-markup">&lt;tc:columnNode/></code> tag can contain several tags for a tree.
      In this example, it's a <code class="language-markup">&lt;tc:treeIndent/></code> to intent the
      single entries of the tree.</p>
