To trigger the Date cell type, use the option type: 'date' in columns array
or cells function. The Date cell uses Pikaday datepicker as
the UI control. Pikaday uses Moment.js as a date formatter.
Note that Date cell requires additional files in your <head> :
/dist/moment/moment.js/dist/pikaday/pikaday.js/dist/pikaday/css/pikaday.css
All data entered to the data-typed cells are validated agains the default date format (DD/MM/YYYY), unless another
format is provided. If you enable the correctFormat config item, the dates will be automatically formatted to
match the desired format.
