    <p>Well, I was trying to obtain the same effect without resorting to fixed size columns or having a fixed height for the entire table.</p> <p>The solution I came up with is a hack. It consists of duplicating the entire table then hiding everything but the header, and making that have a fixed position.</p> <h3>HTML</h3> <pre><code>&lt;div id="table-container"&gt; &lt;table id="maintable"&gt; &lt;thead&gt; &lt;tr&gt; &lt;th&gt;Col1&lt;/th&gt; &lt;th&gt;Col2&lt;/th&gt; &lt;th&gt;Col3&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;tr&gt; &lt;td&gt;info&lt;/td&gt; &lt;td&gt;info&lt;/td&gt; &lt;td&gt;info&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;info&lt;/td&gt; &lt;td&gt;info&lt;/td&gt; &lt;td&gt;info&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;info&lt;/td&gt; &lt;td&gt;some really long line here instead&lt;/td&gt; &lt;td&gt;info&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;info&lt;/td&gt; &lt;td&gt;info&lt;/td&gt; &lt;td&gt;info&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;info&lt;/td&gt; &lt;td&gt;info&lt;/td&gt; &lt;td&gt;info&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;info&lt;/td&gt; &lt;td&gt;info&lt;/td&gt; &lt;td&gt;info&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;info&lt;/td&gt; &lt;td&gt;info&lt;/td&gt; &lt;td&gt;info&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;div id="bottom_anchor"&gt;&lt;/div&gt; &lt;/div&gt; </code></pre> <h3>CSS</h3> <pre><code>body { height: 1000px; } thead{ background-color:white; } </code></pre> <h3>javascript</h3> <pre><code>function moveScroll(){ var scroll = $(window).scrollTop(); var anchor_top = $("#maintable").offset().top; var anchor_bottom = $("#bottom_anchor").offset().top; if (scroll&gt;anchor_top &amp;&amp; scroll&lt;anchor_bottom) { clone_table = $("#clone"); if(clone_table.length == 0){ clone_table = $("#maintable").clone(); clone_table.attr('id', 'clone'); clone_table.css({position:'fixed', 'pointer-events': 'none', top:0}); clone_table.width($("#maintable").width()); $("#table-container").append(clone_table); $("#clone").css({visibility:'hidden'}); $("#clone thead").css({'visibility':'visible','pointer-events':'auto'}); } } else { $("#clone").remove(); } } $(window).scroll(moveScroll); </code></pre> <p>See here: <a href="http://jsfiddle.net/QHQGF/7/" rel="noreferrer">http://jsfiddle.net/QHQGF/7/</a></p> <p>Edit: updated the code so that the thead can receive pointer events(so buttons and links in the header still work). This fixes the problem reported by luhfluh and Joe M.</p> <p>New jsfiddle here: <a href="http://jsfiddle.net/cjKEx/" rel="noreferrer">http://jsfiddle.net/cjKEx/</a></p>

    1. CONice example! Thank you, I'll use it. But wouldn't it perform better by clonning only <thead> and putting it into a <table> tag? You know, there may be a lot of elements in original table.

    2. COI tried that first, the problem with that is that the size of the elements in the header depend on the contents of the table. If you have a row with big content the entire column, including the header will grow. If you clone just the thead you lose that information and you don't get the desired effect. See Yzmir Ramirez's comment on the accepted answer. This is the only way I found that works without fixed width columns. It isn't clean, I know, which is I way I said it was a hack.

    3. COOh, I got it. This method is great because it works with fluid columns, I googled a little and couldn't find another one with that functionality. Anywhay, if i'll get it done somehow, I'll mention it here

Querying!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
