Make column editable

[sachabruttin]

Please add support for editing.

Currently there is no way to add 'editable = true' and 'editrules' and 'editoptions' are missing too...

Hi sachabruttin,

Thanks for your interest in our helper, we didn't implemented editable at this point.

We accept pull requests, so if you really need this feature you can make a pull request with the changed code and tests for it.
