To trigger the Date cell type, use the option type: 'date' in columns array
or cells function.
The Date cell uses jQuery UI Datepicker as
the UI control. You can configure the datepicker by applying jQuery
UI
Datepicker API properties in the same columns array
or cells function
Note that Date cell requires additional files in your <head>:
