I'm using rows group in ag-grid,

Is it possible to sort the group column by the row count?

As follow:

You need to define custom sorting:

const gridOptions = {
    columnDefs: [
        {
            field: 'age',
            // simple number comparator
            comparator: (valueA, valueB, nodeA, nodeB, isInverted) => valueA - valueB
        },
        {
            field: 'name',
            // simple string comparator
            comparator: (valueA, valueB, nodeA, nodeB, isInverted) => {
                if (valueA == valueB) return 0;
                return (valueA > valueB) ? 1 : -1;
            }
        }
    ],

    // other grid options ...
}
