Hi @danextian I got it.
I have to change this part and put the attribute and order of this.
{
"type": "window",
"ops": ["row_number"],
"fields": [null],
"as": ["index"],
"sort": {
"field": "party_sort",
"order": "descending"
}

Hi @Merinoide ,
It looks like your party sort column is not in the correct data type. It is a text string instead of a number. A number column would be italicized and right aligned. Try chaging the data type in Power Query and see it goes.
The number columns below are italicized and right-aligned.
Hi @danextian thanks for your answer.
Looks like that the type of value it's not the reason
I changed this but... nothing
