    <h1>A (virtualized) grid for you!</h1>


    <section>
      Row virtualization allows you to render large quantities of data without putting large quanitites of
      DOM elements into the page.  This essentially works by mutating the data that is bound to each row as the view
      scrolls.  The table is really just made up of the rows you see in the page plus a small buffer on each side.
      Once a full "page" of data is scrolled off the page, the rows shift back up to the top of the buffer and recycle.

      <br/>
      <br/>

      Using the following data:
      <br/>
      <br/>
      <script src="https://gist.github.com/sayeefb/5e687edd0a7660663cfb.js"></script>
      <br/>
      And this snippet of html and javascript:
      <br/>
      <br/>
      <script src="https://gist.github.com/sayeefb/85a64c18cc0fa3e6d501.js"></script>

      You too can make a spectacular virtualized table!
      <br/>
      <br/>

      <ui-grid rowheight="50" height="400" selectionEnabled="true" multiSelect="true"></ui-grid>


    </section>

    <section>
      <h2>Cell Templating</h2>

      The first example is great but it only programmatically renders each cell the same.
      Cell templating allows us to customize each column independently.

      <br/>
      <br/>

      <script src="https://gist.github.com/sayeefb/fbad904d87278ab8f33d.js"></script>

      Now marvel at this spectacular sight!

      <br/>
      <br/>

      <ui-grid rowheight="50" height="400">
        <template column-override name="a">
          <b>&#9829;{{model.a}}</b>
        </template>
      </ui-grid>

      <br/>

    </section>

    <section>
      <h3>Todo</h3>

      So there is bunch of stuff that we need to finish up on this.

      <ul>
        <li>Multi-sort (Need to port solution from consultations) <a href="https://github.com/glg/consultations/blob/starphleet/public/js/controllers/dashboards/Volumizer.coffee#L90">Linked!</a></li>
        <li>Header template overrides (Copying column override code)</li>
        <li>Resizeable column widths using core-resizeable</li>
      </ul>

    </section>

  </body>

  <script>
    document.addEventListener('polymer-ready', function() {
      var tables = document.querySelectorAll('ui-grid').array();

      tables.forEach(function(table) {
        var data = [];

        for (var i = 0; i < 1000; i++) {

          var keys = [ 'a', 'b', 'c', 'd', 'e', 'f' ];
          var row = keys.reduce(function(acc,key,j) {
            acc[key] = key+i;
            return acc;
          },{})

          data.push(row);
        }

        table.value = data;

        var events = [
          'cellclick',
          'celldblclick',
          'headerclick',
          'headerdblclick',
          'gridvaluechanged'
        ]

        events.forEach(function (event) {
