Whilst your reply was very helpful and has pointed me in the right direction, I was wandering whether you could help me further?
I do not want to override the sorting algorithm for the grid, especially as the sorting algorithm for dates is quite complex and jqWidgets does it brilliantly… Instead, what I would like to do is treat any none date value in the column as a date of 00-January-0000 00:00. Effectively the cell would have a date value but display as a string. Is this possible?
Alternatively, could I instead override the sort function with my own (as you have suggested) to simply separate the strings from the dates, and then call the jQWidgets sort method to sort the dates, then I could simply add my strings to the end or the beginning of the data table? In other words, is it possible and how can I call the JQWidgets sort method on an array or object containing custom data?
Thanks in advance
