    <p>(Looked at a bunch of answers on this topic, none of which applies to this question.)</p> <p>The DataTables have the feature of letting the user click on each column's Up/Down triangle icons to sort in Ascending or Descending order. I have loaded the data as follows</p> <pre><code> oTable.fnAddData( ["Bogus data","1,541,512","12.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","3,541,512","2.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","541,512","1.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","2,541,512","32.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","741,512","3.5%","0","0","0"]); oTable.fnAddData( ["A Bogus data","41,512","1.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","2,541,512","12.5%","0","0","0"]); oTable.fnAddData( ["Z Bogus data","1,541,512","12.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","3,541,512","2.5%","0","0","0"]); oTable.fnAddData( ["La Bogus data","541,512","1.5%","0","0","0"]); oTable.fnAddData( ["The Bogus data","2,541,512","32.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","741,512","3.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","41,512","1.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","2,541,512","12.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","1,541,512","12.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","3,541,512","2.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","541,512","1.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","2,541,512","32.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","741,512","3.5%","0","0","0"]); oTable.fnAddData( ["Bogus data","41,512","1.5%","0","0","0"]); </code></pre> <p>In column number 2 the numeric values are processed alphabetically when I click on the Up/Down triangles. How can I adjust it so that the second column Up/Down arrows will trigger the proper way, treating the characters as numbers. I tried using the following initialization:</p> <pre><code>oTable = $('.utable').dataTable( { "aoColumns": [{ sWidth: '60%' },{sWidth: '30%', "sType": "numeric"},{ sWidth: '10%' }], "sDom": 'rt', "sScrollY":"200px", "bPaginate":false, "bFilter":false, "bInfo": false}); </code></pre> <p>All this does is to lock the colum and the Up/Down icons will not work in the header of that column. </p> <p>Please help</p> <p>DKean</p>

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.

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