HtmlTable.Sort doesn't work with multiple rows in <thead>

Reported by Tristan | July 9th, 2010 @ 12:41 PM | in

It seems that HtmlTable.Sort is unable to cope with multiple rows in the part of a table. I have made a MooShell example to illustrate the problem.

You will see that when you try to sort one of the subheaders that Firebug will tell you this error:

Index or size is negative or greater than the allowed amount" code: "1
var head =[index]);
mootoo...more.js (line 6967)

    This is caused by the HtmlTable class, which sets this.head =[0]);

    So, currently if you have 2+ rows in the theader, the first row will work. Others find a -1 index since their index are not found in this.thead. I would change this.head to be all ths, but I'm not sure how that will affect other classes that use Class.refactor on HtmlTable.

    Consider this: When I click "Head 2" what is supposed to sort? The first column (1,5,3) or the second (Green, Yellow, Blue)? I'd need a pretty convincing argument that this is in fact within the scope of HTMLTable. You can create whatever wild table header you want and it'd be impossible to guess what is the intended behavior.

    However, maybe there's a valid argument to be able to pass as an option a collection of elements whose indexes match the rows you want to sort.

    My how quickly my opinion changes.

    I just needed to have multiple th's in a sortable table. I've implemented what I think is a good solution. Just need to get testrunner working on my machine so I can create the tests and then push the changes to my fork.

    Essentially just created a thSelector option to tell the class which th's ought to be clickable that defaults to th. So if you wanted you could do something like

    thSelector: 'thead > tr:first-child > th'

    Another option (I just thought of now) would be to pass in either a selector (like I just explained) or a collection of elements. Those elements have to be in the same order as the columns. Then, put in a check somewhere of the argument type, if it's a collection of Elements, attach the events to the elements (though not sure how delegation fits in here, I'm going to chew on that for a bit.)

    Not sure about this one. Example doesn't work anymore either. Would be nice to see a new example on!

    Ryan's solution sounds rather clean. Will leave this up to Aaron for after the first 1.3-release.

    Ryan, I believe you have the test runner working now. Can you send a pull? We'll aim for as stated.
