</code-sandbox><p>As seen above, the showcase includes a combination of features and extensions which allow Grid to support any data types as well as data visualization.</p>
<p>The most commonly used features have been included in this showcase, such as sorting, filtering, and column moving. </p>
<p>The extensions show how they can leverage Grid so it can support many use cases. The following offers a brief explanation about some of their usage:</p>
<ol>
<li><code>In-cell Editing Extension</code> allows the data manipulation to be made, under the 'Name' and 'Bought' columns, any row-data in any type can be changed.</li>
<li>By clicking on the button under the 'Country' column, will a dialog box pops up, showing the full country name using the <code>Formatter</code>.</li>
<li><code>Heat Map Extension</code> uses in the 'Bank Balance' column to provide the coloring for the columns field to present the balance health.</li>
<li><code>Percent Bar Extension</code> uses in the 'Rating' column allow the showcase to render the data in the bar.</li>
<li>By scrolling to the right panel of the Grid, <code>Conditional Coloring Extension</code> applies to differentiate the percentage values making it easy to analyze the data.</li>
<li>The 'Group By' dropdown option utilizes an additional UI customization with the Grid's API extension in this showcase resulting an useful UI feature as a ef-pill.</li>
<li>The total data size option for the data rendering can also be adjusted to see the performance of the <code>row virtualization</code> feature.</li>
</ol>
