How to sort Date/Time column in angular 4 material sort?

Question

I\'m using angular material table and using matSort for sorting. But it\'s not sorting the dates/time column. It takes the datetime column values as strings.

How to sor

Answer 1

The easiest way to sort on a date in the Material Table is converting your date to a Unix timestamp in the sortingDateAccessor.

this.dataSource.sortingDataAccessor = (item, property) => {
        switch (property) {
            case 'birthday':
                return new Date(item.birthday).getTime()

            default:
                return item[property]
        }
}
