I planned to give all date strings that are in the past a red color and all other ones the default one (black). So my attempt was on creating a custom formatter that works as a hook to the date formatter (currently without date comparison):
If you use custom formatter you should custom unformat the value when you edit. If you use the inline editing I think the best place for this is to use datInit event in edit options in colModel.
dataInit : function (elm) {
// here the code to remove the span if available in the input elm value
}
Also I found a little bug, so you will need to download the latest code from GitHub.
