Error in "DataTables highlighting example"

Hi there,
I was looking for a highlight row axample and noticed that "DataTables highlighting example" ( http://datatables.net/release-datatables/examples/api/highlight.html ) displays wrong column as highlighted.

It actually highlights the column next after the one where mouse cursor is located.
If the cursor is on the last column, datatable highlights the first column.

I am not sure if there is a bug in the core or the example has it, but anyway want to bring your attention to it.

    lol - thanks for that! The bug is in the line:

    [code]
    $('td:nth-child('+(iCol+1)+')', nTrs)
    [/code]

    that +1 has no business being there...! I'll get this fixed - thanks for the heads up!

    was there a change in jQuery? I don't remember which, but some of their functions were 1-indexed (for uniformity with the DOM library, I think), while most were 0-indexed. this might have been one of them and perhaps they changed it recently.

    That would make sense - I'm sure I wouldn't have committed in the column highlighting doing some obviously wrong. I wonder if nth-child has been slightly changed in one of the newer versions - which looks at it looks like a good change to me!

    Nope - it was me... The example was ropey... I had:

    [code]
    $('td').index(this);
    [/code]

    should have been:

    [code]
    $('td', this.parentNode).index(this);
    [/code]

    Doh! Its a wonder it was only off by one column... Example fixed and commit just about to go to github. Weirdly it worked on my local server, but not datatables.net - can't explain that. However, both happy now!

    Thanks for spotting that!
