Need to add sorting from smallest to largest and vice versa for the deps and amount fields.

Is it possible to add a filter to child columns using :sort-by?
I didn’t find a similar example in the documentation for sorting by children columns

Multi sort

example const header

[
    {
        "title": "Net",
        "key": "utmcompagin"
    },
    {
        "title": "04-29",
        "key": "2024-04-29",
        "align": "center",
        "children": [
            {
                "title": "Amount",
                "value": "2024-04-29 Amount"
            },
            {
                "title": "Deps",
                "value": "2024-04-29 Deps"
            }
        ]
    }
]

<v-data-table
                :headers="headers"
                :items="tableData"
                height="1000"
                sticky
                :items-per-page="-1"
                :items-per-page-options="[-1, 10, 20, 50]"
                density="compact"
                class="elevation-1"
                :search="search"
                :loading="loading"
              >
