    <p>My own suggestion, would be:</p> <pre><code>$(".ordinal").text(function (i, t) { i++; var str = i.toString().slice(-1), ord = ''; switch (str) { case '1': ord = 'st'; break; case '2': ord = 'nd'; break; case '3': ord = 'rd'; break; case '4': case '5': case '6': case '7': case '8': case '9': case '0': ord = 'th'; break; } return i + ord; }); </code></pre> <p><a href="http://jsfiddle.net/davidThomas/BMTxa/2/" rel="noreferrer">JS Fiddle demo</a>.</p> <p>This effectively takes the incremented number (<code>i++</code>, in order to start from <code>1</code> not <code>0</code>), converts it to a string, then looks at the last number of that string. This <em>should</em> work for any number, since the ordinal is based purely on that last number.</p> <p>You could also extend the <code>Number</code> prototype to implement this functionality:</p> <pre><code>Number.prototype.ordinate = function(){ var num = this + 1, last = num.toString().slice(-1), ord = ''; switch (last) { case '1': ord = 'st'; break; case '2': ord = 'nd'; break; case '3': ord = 'rd'; break; case '4': case '5': case '6': case '7': case '8': case '9': case '0': ord = 'th'; break; } return num.toString() + ord; }; $(".ordinal").text(function (i, t) { return i.ordinate(); }); </code></pre> <p><a href="http://jsfiddle.net/davidThomas/BMTxa/3/" rel="noreferrer">JS Fiddle demo</a>.</p> <p>Edited to offer a slight alternative:</p> <pre><code>Number.prototype.ordinate = function(){ var num = this, last = num.toString().slice(-1), ord = ''; switch (last) { case '1': ord = 'st'; break; case '2': ord = 'nd'; break; case '3': ord = 'rd'; break; default: ord = 'th'; break; } return num.toString() + ord; }; $(".ordinal").text(function (i,t) { return t.replace(/(\d+)/g, function(a){ return parseInt(a, 10).ordinate(); }); }); </code></pre> <p><a href="http://jsfiddle.net/davidThomas/BMTxa/7/" rel="noreferrer">JS Fiddle demo</a>.</p> <p>This essentially iterates over each <code>.ordinal</code> element, replacing the numbers present with the (same) numbers with the ordinal suffix added to it.</p> <hr /> <p><strong>Edited</strong> to address the problem, raised in the comments, below, that <code>11</code>, <code>12</code> and <code>13</code> were receiving the ordinal suffix of <code>st</code>, <code>nd</code> and <code>rd</code> (respectively). This is now corrected to being <code>th</code> in all cases:</p> <pre><code>Number.prototype.ordinate = function(){ var num = this, numStr = num.toString(), last = numStr.slice(-1), len = numStr.length, ord = ''; switch (last) { case '1': ord = numStr.slice(-2) === '11' ? 'th' : 'st'; break; case '2': ord = numStr.slice(-2) === '12' ? 'th' : 'nd'; break; case '3': ord = numStr.slice(-2) === '13' ? 'th' : 'rd'; break; default: ord = 'th'; break; } return num.toString() + ord; }; </code></pre> <p><a href="http://jsfiddle.net/davidThomas/BMTxa/11/" rel="noreferrer">JS Fiddle demo</a>.</p> <p>References:</p> <ul> <li><a href="https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Array/slice" rel="noreferrer"><code>slice()</code></a>.</li> <li><a href="https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Statements/switch" rel="noreferrer"><code>switch()</code></a>.</li> <li><a href="http://api.jquery.com/text/" rel="noreferrer"><code>text()</code></a>.</li> <li><a href="https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Object/toString" rel="noreferrer"><code>toString()</code></a>.</li> </ul>

    1. COThis looks interesting, thank you David, but it doesn't seems to attach 1st, 2nd, 3rd, etc. to the 1st row, 2nd row, 3rd row, etc. I would like the "st", "nd", "rd" attached to the number in table cell. I couldn't get that to work, is there a way to do that?

    2. COYes, that's exactly what happens for me, under Chrome 25/Win XP. What browser/platform are you using that fails? (I'm unable to test with IE, since IE<8 fails JS Fiddle as a whole.)

    3. COOh boy, I reread my comment, and it is pretty confusing, I apologize. The sentence was supposed to mean "it seems to attach...". The point, however, is that I don't want the cells of the table numbered in sequence but simply the number within the cell shown as an ordinal. Does that make more sense? I apologize for my previous unclear comment. I tested it on Chrome 26/Win 7.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
