Sort datatable by number

[maximilianfixl]

How can I sort q-datatable by default?
For example I need to sort the ID column by DESC.
I tryed to use the sort(a, b) method, but not successful.

I tryed to use in columns array

...
{
  label: 'ID',
  field: 'id',
  width: '4%',
  filter: true,
  sort (a, b) {
    return (a - b);
  },
  type: 'number'
},
...

Any ideas how to solve or explain it to me?

  sort: true,
  type: 'number'
},

What makes it different than my code? That column sort’s ASC by id and not the other way round. I need to sort it from 999 on the top to 1 on the bottom. I was looking for the DESCENDING way.

Oh!

Prety sure you can reverse the order by clicking. But for the sort function, simply reverse the order of the argumens bieng compared. so b - a instead of a - b

That’s what I tryed as well. But it has no effect. I go ahead! Will let you know, if I figured it out.
