Datatable: Date sorting is working only on it own with multiple sorting

[alpiua]

Describe the bug

When I try to sort on multiple columns, the column in Date format after been selected, prevents any other column from being sorted.

Steps to reproduce the behavior

1. Create datatable component with multiple sorting columns
2. Select column with Date type in it
3. See that sorting in other columns is not working at all

Expected behavior

I expect to see a working sorting for any column in any order chosen.

Add .getTime() to your dates to use unix timestamp and it will work.

const dummyData = [
  {
    date: new Date(2023, 2, 10).getTime(), // May 15, 2023
[...]

PrimeVues datatable can't compare objects when multisorting, hence you have to provide a string.

Thank you, now I get it. I believe the documentation would benefit from including this.
