    copied!<p><strong>Scrolling</strong></p> <p>I won't dig deep into GWT with this post but I'll try to give some hints on how to do the scrolling part.</p> <p>If your table's data is wrapped in a separate tag than the table's body, then it shouldn't be a problem. If the table's structure is similar to the following, it shouldn't be a problem:</p> <pre><code>&lt;table&gt; &lt;thead&gt; &lt;tr&gt; &lt;th&gt;ColumnHeader1&lt;/th&gt; &lt;th&gt;ColumnHeader2&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;tr&gt; &lt;th&gt;Data1&lt;/th&gt; &lt;th&gt;Data2&lt;/th&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; </code></pre> <p>To make the data part vertically scrollable, you should add a CSS style to the <code>&lt;tbody&gt;</code> element which sets <code>overflow-y: scroll;</code> when the rowcount is greater than 15. Also you need to set the height or limit it's height by other means (wrapping container) for the scrollbar to appear.</p> <p>To set the height, I'd consider to get the <code>&lt;tbody&gt;</code>'s offset height right after the 15th row has been added and force it to stay at that. It might go like this:</p> <pre><code>tbodyElement.setHeight(tbodyElement.getOffsetHeight()); </code></pre> <p>Remember, this has to be done right after adding the 15th row.</p> <p><strong>Sorting</strong></p> <p>For that you should wrap your column header names in some kind of a <code>Widget</code>. It could be a <code>HTML</code> or a <code>Label</code> for example. You just need to add <code>ClickHandler</code>s to them and some styling to fill the whole cell and the cursor to switch to a hand with CSS <code>cursor: pointer;</code> while hovering on it.</p> <p><strong>Conclusion</strong></p> <p>Well, this was my light overview of this. Without seeing the code you've done it's hard to go any further.</p>
