Auto Expand

This sample shows how you can auto expand the table range using the UI operations. For example, click in cell E5 (‘Sales Manager’) then press the TAB key. A new row will automatically be added. Refer to the description below for further options.

<p>Users can automatically expand the table range by adding data or using copy-paste, drag-fill, and drag-drop actions. Depending on the action, a new table column will be inserted to the right of the table or a new table row will be added below the last row.</p> <p>  1. Add data immediately to the right of a table column or after the last table row.</p> <p>  2. Paste data that exceeds the current table range.</p> <p>  3. dragfill from a table range.</p> <p>  4. dragdrop a range to table range.</p> <p>You can disable/enable the auto expand function by using <strong>allowAutoExpand</strong>. You can also get the toggle state of auto expand by this API.</p> <pre><code class="hljs javascript language-javascript"> table.allowAutoExpand(<span class="hljs-literal">true</span>); <span class="hljs-comment">// Allow the table auto expand.</span> table.allowAutoExpand(<span class="hljs-literal">false</span>); <span class="hljs-comment">// Don't allow the table auto expand.</span> table.allowAutoExpand(); <span class="hljs-comment">// Get the toogle state of auto expand.</span> </code></pre>
