Moving the Length Selector into a table construct

Dear community,

What I'd like to do is to create a plain HTML table inside the top of the datatables in order to align further elements (e.g. advanced filter options) in the datatables top.

To get you an idea of what I want to achieve I've uploaded a screenshot of the current state:

The textboxes, labels and the search button, all are inside a table. My question now is, how to I achieve that I get the Length element (Show ... entriue) also into a column of the table i've injected into the datatables top?

The code actually looks like this:

oTable = $('#example').dataTable({
                "bJQueryUI": true,
                "sDom": '<"H"l<"searchBarDiv">>t<"F"ip>',
                [...]
});
// contains the table structure
var sSearchBarContent = $('#SearchPersonFAInfoSearchDiv').html();
$('div.searchBarDiv').html(sSearchBarContent);
$('#SearchPersonFAInfoSearchDiv').remove();

During some search I found a ways which allows to completly rewrite the Length Element: https://datatables.net/forums/discussion/13788/request-custom-length-control-plugin-using-instead-of-/p1
But actually I do not want to customize it, but to position e.g. to wrap it by a table.

Hope for further help.

Best regards

Samuel
